Multiquip PSVFF303P Vacuum Fuel Lock with Primer - OEM Replacement Part

The vacuum fuel lock with primer controls propane vapor flow from the tank to the engine on propane-powered equipment, providing critical fuel system shutoff and priming capability for reliable cold starts and safe operation. This component is essential for maintaining proper fuel delivery in propane vapor withdrawal systems.

Designed specifically for the WBH-21EFP power buggy, this vacuum fuel lock integrates with the specialized vapor withdrawal propane system that uses a green-banded tank with ACME left-hand threaded fittings. The WBH-21EFP operates with a 33.5 lb propane vapor tank (filled to 80% capacity at 26.8 lbs) and requires vapor-specific components—liquid propane system parts will cause damage and must never be substituted. The integrated primer enables manual fuel system pressurization for starting, particularly important in cold weather conditions or after tank changes.

This fuel lock is a critical safety and operational component for the WBH-21EFP, which is rated for 3,200 lb maximum capacity with hydrostatic drive and speeds up to 7.25 mph. Failed fuel locks typically cause hard starting, engine stalling, or inability to maintain consistent engine speed under load.
