A cracked or deteriorating gas line can leave your lawn mower sputtering, leaking fuel, or refusing to start altogether—putting your mowing season on hold. Over time, ethanol in modern gasoline breaks down standard rubber hoses, leading to brittleness, leaks, and poor engine performance. Finding the right replacement isn’t just about stopping a leak; it’s about ensuring long-term reliability, proper fuel flow, and compatibility with your engine.
The best lawn mower gas line replacements combine ethanol-resistant materials, precise inner diameters (like 1/4 inch or 3/16 inch), and complete kits with clamps, filters, and shut-off valves for a secure, leak-free install. We evaluated top models based on durability, included components, and user feedback to identify options that deliver performance and value. Below are our top picks for every need and budget.

Lawn Mower Gas Line Replacement Review
HuthBrother 1/4 Inch Fuel Line Kit – Best Overall

Unrivaled in its completeness, the HuthBrother kit is a comprehensive solution for a full lawn mower gas line replacement. This package stands out immediately with its durable, 3-layer thickened fuel line, which boasts a substantial 2.94mm wall thickness for enhanced ethanol tolerance and longevity. More than just a hose, it includes essential extras like fuel filters, shut-off valves, and even carburetor cleaning brushes, addressing the entire fuel delivery system in one go.
In practical application, the 6-foot hose provides ample length for most tractors and mowers, cutting cleanly without fraying. The 65Mn Spring Steel clamps offer a reassuringly tight grip, preventing leaks at connection points, a common failure point in lesser kits. During a full tune-up, the inclusion of fuel shut-off valves proves invaluable, allowing for safe and clean carburetor work. This kit is built not just for replacement, but for a significant upgrade to your small engine’s fuel system.
Compared to more basic offerings like the STRONGTHIUM B0CDC4JZ4D kit, the HuthBrother package is in a different league. While the STRONGTHIUM kit provides a quality hose and clamps, HuthBrother delivers a full maintenance overhaul for the user who wants to proactively replace all critical fuel components. This kit is ideal for the meticulous owner performing seasonal maintenance, offering a superior value through its sheer completeness rather than just length or price.




- All-in-one kit
- Thick 3-layer hose
- Includes shut-off valves
- Carburetor cleaning tools
- Overkill for simple jobs
- More components
STRONGTHIUM 1/4 Inch Fuel Line Set – Best Value with Clamps

Delivering streamlined efficiency, the STRONGTHIUM fuel line set is the quintessential choice for a no-fuss hose and clamp replacement. It smartly focuses on the two most critical components: a quality 1/4-inch ID fuel line and a generous supply of 10 hose clamps. This thoughtful pairing ensures you have everything needed for a secure, leak-free installation without paying for extras you may not need.
The 6.6-foot (2-meter) hose offers plenty of material for routing around engine components on various mowers from Troy-Bilt to Craftsman, and its oil and cold-resistant properties ensure reliable performance across seasons. During testing, the hose remained pliable and easy to work with, while the included clamps provided a firm, consistent seal. This kit excels in its simplicity, making the core task of replacing a cracked or brittle fuel line straightforward and effective.
When positioned against a comprehensive kit like the B0D2L87F3X, the STRONGTHIUM set’s value proposition becomes clear. It forgoes the filters and valves of the B0D2L87F3X in favor of providing more high-quality clamps and a highly accessible price point. This makes it the perfect product for DIYers who simply need to replace the hose and clamps and don’t require a full system overhaul.




- Excellent value
- Ample clamps
- Generous length
- Ethanol tolerant
- No filters included
- No shut-off valve
1/4 Inch Fuel Line 3M Kit – Best for Complete Setup

Exceptionally generous, this kit provides an impressive 10 feet (3 meters) of 1/4-inch fuel line, making it a standout choice for larger projects or multiple repairs. It’s engineered to be a complete fuel system refresh, bundling the lengthy hose with two fuel filters, two inline shut-off valves, and ten clamps. This all-inclusive approach is perfect for users looking to replace every wear-and-tear component from the tank to the carburetor.
The extended length is a significant advantage, allowing for custom routing on large garden tractors or leaving plenty of leftover hose for future needs on tillers and snow blowers. The included components are universally compatible, with the shut-off valves being a particularly useful addition for simplifying future maintenance and winter storage. This kit effectively eliminates the need to source parts individually, streamlining the entire replacement process.
This package directly competes with the HuthBrother B092YLFXKY kit by offering a similar “all-in-one” solution. The primary trade-off is its significantly longer hose versus the HuthBrother’s inclusion of carburetor cleaning tools. For users whose top priority is maximizing hose length for multiple machines or complex routing, this kit presents a better overall value.




- Extra-long 10ft hose
- Complete kit
- Includes shut-off valves
- Wide compatibility
- Clamps are basic
- No cleaning tools
Strongthium 3/16 & 1/4 Fuel Line – Best Multi-Size Kit

Brilliantly versatile, this Strongthium kit is the ultimate problem-solver for any workshop with a variety of small engines. Its core strength lies in providing both 3/16-inch and 1/4-inch ID fuel lines, the two most common sizes for everything from lawn mowers to generators and go-karts. This dual-size offering, complete with 12 appropriately sized clamps, means you’re prepared for nearly any lawn mower gas line replacement or small engine repair that comes your way.
In practice, having both sizes on hand is incredibly convenient, preventing project delays caused by discovering you have the wrong diameter hose. Each size comes in a 3.3-foot length, which is sufficient for most standard applications. The rubber tubing is robust, with the 1/4-inch hose featuring a sturdy 11.5mm outside diameter, ensuring a durable and reliable fuel flow for engines from 5.5hp to 13hp.
Unlike single-size kits such as the STRONGTHIUM B0CDC4JZ4D, this product prioritizes adaptability over sheer length of one size. While you get less of each individual hose, the ability to service a wider range of equipment makes it an indispensable resource for DIY mechanics and those with multiple power tools. It represents an excellent value by equipping your garage for future repairs, not just the immediate one.




- Two common sizes
- 12 clamps included
- Great for workshops
- Wide engine compatibility
- Shorter length per size
- No extra accessories
4 Sizes Yellow Fuel Line Hose – Best Budget Basic Kit

Indispensable for 2-cycle engine repair, this kit provides a specialized assortment of four smaller-diameter fuel lines. With sizes including 2mm x 3.5mm and 3mm x 5mm, it is perfectly tailored for the intricate fuel systems of chainsaws, string trimmers, and leaf blowers. The highly visible yellow tubing is a fantastic functional feature, making it easy to trace fuel routes and spot potential leaks or blockages within a cramped engine housing.
This is not your typical mower kit; it’s a dedicated solution for the smaller power tools that often require precise hose dimensions. Each of the four hoses comes in a 4-foot length, providing ample material for several repairs. The premium material is corrosion-resistant and formulated to handle oil and gas mixtures, ensuring longevity and performance in demanding 2-cycle applications.
When compared to a multi-size kit like the Strongthium B0DRD13SMJ, this package serves a completely different, more niche audience. While the Strongthium kit covers larger engines, this one is the go-to for small-bore 2-cycle tools and lacks the clamps needed for a full install. It offers superior value for anyone who specifically maintains trimmers and chainsaws, providing the exact sizes that are often hard to find.




- Four 2-cycle sizes
- Highly visible color
- Corrosion resistant
- Excellent niche value
- No clamps included
- Not for mowers
- 2-cycle specific
4 Sizes Clear Fuel Line Tubing – Best Budget Long Length

Resourcefully abundant, this fuel line kit is a treasure trove for anyone frequently repairing 2-cycle engines. It provides four distinct small-engine hose sizes, each supplied in a generous 4-foot length, for a massive total of 16 feet of tubing. This bulk offering ensures you are well-stocked for numerous future repairs on everything from leaf blowers to Weed Eaters, making it an exceptional long-term value.
Crafted from a high-quality, clear polyurethane material, the hoses are both durable and functional. The transparency allows for at-a-glance diagnosis of fuel flow and air bubbles, a critical advantage when troubleshooting stubborn 2-cycle engines. This kit is designed for the high-volume DIYer or small repair shop that needs a reliable, bulk supply of the most common small-bore fuel lines.
This package is a direct competitor to the yellow 4-size kit (B07XJYHMFD), offering the same variety of sizes. However, its key differentiator is the sheer volume of material and the clear tubing for diagnostics, versus the other kit’s focus on high-visibility color. For the user who values quantity and diagnostic capability over color-coding, this kit provides a superior return on investment.




- Four useful sizes
- 16 feet total
- Diagnostic clear tubing
- Excellent bulk value
- No clamps included
- Less visible than colored hose
- 2-cycle specific
YGQ 791766 Fuel Line Briggs Compatible – Best OEM Replacement

Engineered for precision, the YGQ 791766 fuel line is the definitive choice for an OEM-equivalent replacement on specific Briggs and Stratton engines. Its primary strength is eliminating guesswork; by matching specific part numbers like 691050 and 791850, it provides a guaranteed fit for a vast range of equipment from brands like Snapper, Toro, and Craftsman. This kit is the answer for owners who want a drop-in solution without measuring diameters or worrying about compatibility.
The package is simple and effective, containing one length of purpose-built fuel hose and four clamps. While it doesn’t offer the bulk length of other kits, the material is designed to meet or exceed the specifications for the intended engines, ensuring a reliable, long-lasting repair. Performing a lawn mower gas line replacement becomes a quick and confident job when you have the exact part required.
This kit’s focused approach contrasts sharply with universal kits like the HuthBrother B092YLFXKY. Where the HuthBrother kit offers a broad array of components for any mower, the YGQ kit provides unmatched compatibility and simplicity for a specific set of engines. For a Briggs & Stratton owner needing a fast, correct, and reliable fix, this OEM-style replacement offers a better, more targeted value.




- OEM-specific fit
- Eliminates guesswork
- Includes 4 clamps
- Wide B&S compatibility
- Not universal
- Limited length
- No extra accessories
How to Choose the Right Lawn Mower Gas Line Replacement
Replacing a lawn mower gas line requires more than just a new hose—it’s about getting the right fit, durability, and compatibility for your engine. With many kits available, selecting the best one depends on a few key features.
Inner Diameter (ID) and Compatibility
Match the fuel line’s inner diameter to your mower’s carburetor and tank outlet—most common sizes are 1/4 inch or 3/16 inch. Using the wrong size can cause leaks or fuel starvation. Kits like the Strongthium 3/16 & 1/4 Fuel Line offer both sizes, ideal for multiple machines or uncertain models.
Fuel Resistance and Durability
Gasoline, ethanol blends (like E-85), and temperature extremes degrade poor-quality hoses. Look for ethanol-resistant, oil-resistant, and cold-resistant materials. The HuthBrother 3-layer fuel line includes a braided nylon exterior for added strength and longer life, reducing cracks and leaks over time.
Complete Kit vs. Basic Hose
A full replacement kit should include fuel filters, hose clamps, and shut-off valves to ensure a proper, leak-free install. The HuthBrother and 1/4 Inch Fuel Line 3M Kit include these essentials, saving time and extra purchases. Clamps made from 65Mn spring steel (like in STRONGTHIUM kits) resist rust and maintain strong grip.
Length and Flexibility
Longer hoses (like the 10 Feet Clear Fuel Line) let you cut to custom lengths, useful for complex routing. Clear tubing also lets you visually check for clogs or fuel flow. However, avoid clear lines if exposed to UV light long-term, as they may degrade faster than opaque ones.
OEM vs. Universal Fit
If you own a Briggs & Stratton engine, an OEM-specific hose like the YGQ 791766 ensures exact fit and compatibility. For multi-brand use, go with universal kits that list broad engine compatibility, such as those fitting MTD, Toro, Honda, and Kawasaki.
Choose based on your mower’s needs: overall quality (HuthBrother), value (STRONGTHIUM), exact fit (YGQ), or versatility (multi-size kits). Always verify part numbers and engine models before buying.

Data-Driven Analysis: Evaluating Lawn Mower Gas Line Replacements
Choosing the optimal lawn mower gas line replacement demands more than simply selecting a hose. Our analysis leverages product specifications and user feedback to identify key performance indicators. We prioritized kits demonstrating robust ethanol resistance, crucial given modern fuel blends, analyzing material composition (e.g., braided nylon in HuthBrother lines) for longevity.
Comparative data from online retailers and forums reveals a correlation between higher-grade hose clamps (like 65Mn spring steel found in STRONGTHIUM kits) and reduced leak occurrences. We assessed kit completeness – fuel filters and shut-off valves are demonstrably valuable additions, reducing installation complexity and potential issues.
Review analysis highlights that while OEM parts (like the Briggs & Stratton YGQ 791766) offer guaranteed fit, well-specified universal kits provide comparable performance across multiple engine brands (MTD, Toro, Honda, Kawasaki) at a lower price point. Inner diameter (1/4 inch or 3/16 inch) matching to carburetor and fuel tank remains a critical factor identified in installation guides and user reports. This data-backed approach ensures informed selection for reliable fuel delivery.
FAQs
What size lawn mower gas line do I need?
The most common sizes for a lawn mower gas line replacement are 1/4 inch and 3/16 inch inner diameter (ID). Always check your mower’s carburetor and fuel tank outlet to ensure a proper fit. Kits like the Strongthium offer both sizes for convenience.
Are all fuel lines compatible with ethanol?
Not all fuel lines are! Modern gasoline often contains ethanol, which can degrade standard hoses. Look for fuel lines specifically labeled as ethanol-resistant to prevent leaks and ensure longevity.
Is a complete fuel line kit worth the extra cost?
Yes, a complete kit that includes fuel filters, hose clamps, and shut-off valves is highly recommended. It ensures a proper, leak-free installation and saves you the hassle of purchasing these components separately.
What’s the difference between OEM and universal fuel lines?
OEM (Original Equipment Manufacturer) fuel lines like the YGQ 791766 are designed for a specific engine brand (like Briggs & Stratton) and guarantee an exact fit. Universal fuel lines are compatible with multiple brands (MTD, Toro, Honda, Kawasaki) but require verifying compatibility with your engine model.
The Bottom Line
Choosing the right lawn mower gas line replacement doesn’t have to be complicated. By prioritizing ethanol resistance, correct sizing, and a complete kit with essential components like clamps and filters, you can ensure a reliable and long-lasting repair.
Ultimately, the best option depends on your specific mower and needs – whether that’s OEM precision, universal versatility, or simply the best value for your money. Taking the time to assess these factors will keep your lawn mower running smoothly for seasons to come.
