(4 Sizes) 2-Stroke Garden Power Tools Fuel Line Replacement Kit. Fuel Hose Fuel Tube for String Trimmer Chiansaw Blower Power Tools with Small Engine, Nitro Engine. (Yellow, 4ft each)

What It Is

This fuel line replacement kit provides 4 feet each of yellow, 2-stroke compatible fuel hose in four common inner diameters (typically 3/16", 5/32", 1/8", and 1/4"). It’s designed to replace cracked, hardened, or leaking fuel lines on string trimmers, chainsaws, blowers, and other small-engine power tools.

Fitment & Compatibility

Before buying, measure your existing fuel line’s inner diameter (ID) and outer diameter (OD) with a caliper or ruler. This kit includes four sizes, so one should match, but you must confirm which size your machine uses. Most 2-stroke engines use 3/16" (4.8mm) or 5/32" (4mm) ID for the fuel line and 1/8" (3.2mm) for the primer bulb return line. Check your tool’s manual or look up the OEM fuel line part number—this is a universal aftermarket kit, not brand-specific. It will not fit 4-stroke engines or machines requiring metric-only sizes (e.g., some Stihl or Husqvarna models use 4.5mm ID). If your tool has a fuel filter, ensure the new line fits the filter’s barb.

Key Things to Know

• Quality: The yellow hose is typically PVC or rubber, rated for ethanol-blended fuel. It’s flexible but may stiffen in cold weather; UV exposure can cause brittleness over time.
• Installation Difficulty: Moderate. You’ll need to remove the old line, cut the new one to length (use a sharp blade for a clean cut), and reattach to the carburetor, primer bulb, and fuel tank. Heat the line slightly with a hair dryer to soften it for stubborn fittings.
• Common Gotchas: The line may be slightly larger or smaller than OEM spec, causing leaks or poor fit. Use a zip tie or small clamp on the carburetor connection if the fit is loose. Don’t reuse old fuel filter—replace it with a new one from the same kit or separately.
• Length: 4 feet per size is generous; you’ll have plenty for one or two repairs. Store unused lengths away from sunlight.

Should You Buy It

Buy this kit if you have a common 2-stroke tool (e.g., Echo, Ryobi, Poulan) and need a cheap, universal fix for a leaking or hardened fuel line. It’s ideal for DIYers who want multiple sizes on hand, but skip it if you need an exact OEM fit for a specific brand or metric-size line—go with a brand-specific replacement instead.
