Frequently Asked Questions

Q: What engines are these 1/4" fuel shut-off valves compatible with?

A: These fuel shut-off valves are compatible with a wide range of small engine equipment, including lawn mowers, riding mowers, garden tractors, ATVs, and generators. They are direct replacements for OEM part numbers 698183, 493960, 698181, 697947, 9494768, 5019H, and 5019K. If your existing fuel valve has a 1/4" inlet and outlet, these are very likely a match.

Q: Why do I need a fuel shut-off valve on my lawn mower or ATV?

A: A fuel shut-off valve allows you to cut off the flow of gasoline from your fuel tank to your engine. This is essential when storing equipment for extended periods, performing carburetor cleaning or maintenance, or replacing fuel line components. It helps prevent fuel leaks, reduces fire hazards, and extends the life of your carburetor by preventing fuel from sitting in it when the machine isn't in use.

Q: How do I install a fuel shut-off valve on a small engine?

A: Installation is straightforward. First, drain or clamp the existing fuel line to stop fuel flow. Then remove the old valve by loosening the fuel line clamps on each side. Slide the new 1/4" shut-off valve into the fuel line in the correct flow direction (usually marked on the valve body), and secure both ends with clamps. Ensure there are no kinks or leaks before starting your engine.

Q: Why does this pack include 5 valves?

A: The 5-pack is designed to offer great value — you can replace valves on multiple machines at once, keep spares on hand for future maintenance, or share them with friends or neighbors who own similar equipment. Having extra valves on hand means you're never caught off guard when one fails unexpectedly.
