Good To Know

Q: Why is my gas tank fuel cock valve petcock leaking when the valve is off? A: Internal rubber seals can degrade over time due to ethanol in modern gasoline, allowing fuel to bypass the valve. Replacing the unit restores a complete, dry shut-off.

Q: Does this petcock include the internal fuel filter straw? A: Yes, this petcock features an integrated mesh filter straw that extends into the tank to catch debris before it can clog your carburetors.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
