Common questions
What size fuel line does this petcock require?

How do I know if this petcock will fit my fuel tank?
This petcock is designed for fuel tanks with 22mm or 3/8-inch inlet ports. You should measure the opening on your tank or consult your bike's service manual to confirm compatibility.
What are the functions of the three knob positions?
The 'on' position allows normal fuel flow, the 'off' position stops fuel flow entirely, and the 'reserve' position accesses a secondary, lower fuel pickup to extend your riding range when the main fuel supply is low.
