Why Choose iFJF Marine Fuel Lines
A cracked or leaking fuel line is a safety hazard and the most common cause of outboard starting issues on the water. Old fuel lines deteriorate from ethanol exposure, UV radiation, and age — causing air leaks that prevent the primer bulb from building pressure. Our marine fuel line kit replaces your entire fuel delivery path with fresh, ethanol-resistant components that ensure reliable starting and smooth running all season long.
Frequently Asked Questions
Q: How do I know if I need a 5/16" or 3/8" fuel line?
A: Most outboards from 4HP to 200HP use 5/16" fuel line. Engines above 200HP or with V6/V8 configurations may require 3/8". Check your existing fuel line or owner's manual to confirm. 5/16" is the standard for the vast majority of recreational outboards.
Q: Can I use this with a built-in fuel tank?
A: This kit is primarily designed for portable fuel tank setups. For built-in tanks, you may need additional fittings. The connectors in this kit use standard Mercury/Yamaha-style quick-connect fittings.
Q: Is this fuel line ethanol-safe?
A: Yes. Our multi-layer fuel hose features a specially formulated inner liner that resists the corrosive effects of ethanol-blended fuels (E10). Unlike older rubber hoses that can delaminate and clog carburetors, this hose is designed for modern fuel formulations.
Q: How do I prime the fuel system with the primer bulb?
A: Squeeze the primer bulb repeatedly until it becomes firm (usually 5-10 squeezes). The bulb should remain firm — if it stays soft or collapses, check for air leaks in the connections or a stuck anti-siphon valve on your fuel tank.
Q: Should I disconnect the fuel line when storing my boat?
A: Yes. For long-term storage, disconnect the fuel line and run the engine until it stalls to clear fuel from the carburetor. This prevents varnish buildup that can clog jets and passages.
