This special fuel valve by Prism Supply fits directly into the 3/4"-18 tank bung originally used on Harley-Davidson Knucklehead and Panhead fuel tanks – ideal for vintage bikes, old-school restorations, and custom projects. It features a 5/16" diameter hose barb and an integrated fuel filter, ensuring clean and reliable fuel delivery. For a snug, leak-proof fit, we recommend using fuel lines with a 1/4" inner diameter.
Fuel flow is controlled by rotating the lower cylindrical operating piece with the two grooves, allowing precise on/off operation without twisting the attached fuel line. The original crossover line can still be used, while the internal through-tank linkage is completely eliminated.
The kit includes two brass sealing washers and a cap for the top of the tank. Available in brass or stainless steel.
