Fuel Hoses, Lines & Pipes
About Fuel Hoses, Lines & Pipes
Fuel hose is a wear part: it hardens, cracks and swells with age, heat and fuel, and a leaking line on a UTV or ATV is a fire risk. This category covers fuel lines sold by the foot, primer lines, hose and clamp kits for particular quads, and a fuel rail for a Polaris.
Fuel line is sized by the figure in the listing, for example 1/8, 3/16 or 1/4 inch, which is normally the inside diameter, so match it to the fittings and the old hose. It is sold in lengths from 3 foot and 5 foot pieces to a 50 foot roll, and in colors such as clear, black and green; clear lets you see fuel moving.
Use only hose made for fuel. Machines with fuel injection run at much higher pressure than carbureted ones, so use hose that is rated for that pressure, not a general low-pressure line. Hose and clamp kits are listed by make and model for a complete replacement. Always replace clamps that have lost their grip.
Brands in this category include Helix, S&S Cycle, All Balls and SP1. For the parts the line connects to, see Fuel Filters, Fuel Valves & Petcocks and Fuel Pumps & Sending Units. Pick your machine in the Ride Finder at the top of the page.
FAQs on UTV and ATV fuel lines
When does fuel line need replacing?
Replace it if it is cracked, hard, swollen, soft or weeping fuel at the ends, or if it smells of fuel. Old hose may look fine from the outside, so flex it and check near the fittings. A leaking fuel line is a fire hazard, so repair it before riding.
What size fuel line do I need?
Check the old line's size or your manual, and match the figure to the fitting. The sizes listed here are 1/8, 3/16 and 1/4 inch. Fuel line is normally sized by inside diameter. A hose that is too loose or too tight will leak or kink.
Can I use clear vinyl tubing as a fuel line?
Only if it is rated for fuel. General tubing can harden, soften or break down when exposed to gasoline. Use hose sold as fuel line, and use clamps made for fuel hose. Fuel-injected machines need hose rated for the system's pressure.
Should I replace the clamps when I replace the fuel line?
Yes, if the old ones are rusted, stretched or weak. A loose clamp can let a line slip off or leak, so use clamps that hold firmly without cutting into the hose. Hose and clamp kits are listed for particular quads.
