Good To Know

Q: How do I know if my YFM needs a vacuum or manual petcock? A: Check whether your original valve has a vacuum hose port, which indicates a vacuum-operated unit. Match the replacement to your existing setup to keep fuel flow working correctly.

Q: Can I install this petcock with basic hand tools? A: Yes, most installations need only a wrench and a drain pan to catch residual fuel. Shut off the tank and allow lines to drain before removing the old valve.

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