Manual Petcock Replacement Kits

Keep your pesky old vintage vacuum petcocks from draining fuel into your crankcase! and ruining your crankshaft and connecting rod

Application chart developed so far:

Available in 34, 44, 46, 46 offset, & 50mm bolt spacing, and 20, 22, and 24mm threaded nut styles. Output spigot to face right, left, down, and back while looking at face plate. For use on most models and other manual petcock replacement applications. Includes bolt on chrome OFF/ON/RES manual petcock and all hardware for easy mounting.

Note: This petcock requires a .550 diameter hole. Every application we have seen requires a slight modification to the tank with either a round file, dremel tool etc to take off approximately 1/16" off each side of the original hole for mounting clearance. This modificaiton WILL NOT render an original petcock disfunctional.

Now included but not shown is a Vacuum petcock hose cap. (This will cover the nipple on the head or intake manifold that the vacuum hose for the previous petcock use to come out of.)
