Common questions
What thread size does this petcock use?
This petcock features a 22mm metric thread, which is standard for many Harley-Davidson Big Twin and Sportster models from 1975 onward, as well as most custom tanks.
Will this fit my custom fuel tank?
If your custom tank utilizes a 22mm metric petcock mount, this unit is designed to fit. Always double-check your tank's thread size before making a purchase.
What does '1/4 NPT right spigot' mean for my fuel line?
The 1/4 NPT right spigot indicates a 1/4-inch National Pipe Thread fuel line connection that exits the petcock to the right side, which is important for proper fuel line routing.
