Frequently Asked Questions
Will this petcock fit my custom fuel tank?
If your tank has a 22mm metric bung, it will fit. Most aftermarket custom tanks use this standard size.
What's the difference between main and reserve mode?
Main mode draws fuel from the upper portion of the tank. Reserve mode draws from the bottom, giving you extra fuel when the main supply runs dry.
Is this a gravity-fed or vacuum-operated petcock?
This is a gravity-fed design — fuel flows down through the spigot without requiring engine vacuum.
Can I use this on a 1974 or earlier Harley?
No — this 22mm petcock fits 1975 and newer Big Twin and Sportster models. Pre-1975 bikes use different fuel-system designs.
