Made in Mainland China.

Key Features

• High-Efficiency Filtration: High-density pleated filter paper core intercepts 99% of fine particles, sediment, and impurities in gasoline. Prevents fuel injector clogging, reduces engine wear, and extends engine lifespan.
• Transparent Visible Shell: Oil-resistant, high-strength polycarbonate (PC) transparent housing lets you monitor internal filter contamination and fuel flow at a glance — so you always know exactly when it's time for a replacement.
• Safe, Leak-Proof Connection: High-toughness, oil-resistant polypropylene (PP) inlet and outlet ports perfectly fit standard 8mm fuel hoses, forming a secure seal to prevent leaks and eliminate fire hazards from fuel spillage.
• Superior Durability: All components are made from corrosion-resistant composite materials that withstand long-term gasoline exposure and temperatures from -20°C to 80°C without warping or deteriorating.
• Universal & Easy Installation: Standard inline structure with an 8mm outer diameter interface. Fits most 250cc–400cc motorcycles, ATVs, lawnmowers, mini-generators, and small gasoline-powered equipment. No modifications needed — simply connect inline to your existing fuel hose.

Frequently Asked Questions

Q: What engine sizes is this inline fuel filter compatible with?

A: This fuel filter is designed for 250cc to 400cc displacement gasoline engines, including motorcycles, ATVs, dirt bikes, enduro bikes, lawnmowers, mini-generators, and other small gasoline-powered equipment with standard 8mm fuel hose connections.

Q: How do I install this motorcycle fuel filter?

A: Installation is simple and requires no special tools or modifications. The filter features a standard inline design — just cut your existing fuel line and connect the filter's 8mm inlet and outlet ports in line with the fuel hose. Ensure the flow direction arrow (if present) points toward the engine. The tight polypropylene connectors form a leak-proof seal automatically.

Q: How do I know when it's time to replace the fuel filter?

A: The transparent polycarbonate shell allows you to visually inspect the filter element at any time. When the yellow pleated filter paper appears dark, discoloured, or clogged with debris, it's time for a replacement. Regular visual checks after every few rides or during routine maintenance are recommended.

Q: Is this fuel filter resistant to gasoline and heat?

A: Yes. All components are manufactured from corrosion-resistant composite materials — the PC shell and PP connectors are fully oil- and gasoline-resistant, and the filter operates reliably in temperatures ranging from -20°C to 80°C without deforming or leaking.
