Frequently Asked Questions

Do I need fittings or clamps to connect this hose?

Yes—you'll need barbed fittings sized for 5/16-inch hose and stainless steel hose clamps on both ends. The hose itself is bare rubber ready to slide over barbed nipples.

Can I use this with my carbureted engine and ethanol fuel?

Yes. NBR rubber is ethanol-resistant and won't swell or degrade on modern E10 fuel blends. It's the standard material for fuel line in carb and EFI builds.

How do I know where to cut the hose?

Measure the distance from your tank outlet to the carb inlet (or fuel rail), then add 2 inches for slack and fitting overlap. Cut with a sharp utility knife or hose cutter for a clean edge.
