Universal Filler Neck Kit for Cab and Chassis

About this part

Universal Filler Neck Kit, fitment-checked

An accessory rather than a tank: the filler neck is the part that gets the fuel in, and on a cab and chassis it often has to be adapted to whatever body is on the back.

Cab and chassis trucks leave the factory without a body, so the route from filler cap to tank depends on what the upfitter built — which is why a universal filler neck kit exists at all. Coverage crosses two manufacturers: the Ford F-350 and F-350 Super Duty, the F-450 Super Duty, and the Ram 3500, all in cab and chassis form and all with year spans that differ from one another. This is one of only two items in the range carrying a Limited Warranty rather than the Lifetime class.
