Our size chart is only based on engine oil drain plugs however, we try to have the specs information for the most popular makes & models. If we miss information is either because we are still working on it, or it's not available.
It is almost impossible to have specs for every single engine out there, so if you cannot find specs for your engine feel free to contact us. If you know the make of the engine, as well as the engine size, we will do our best to help you find a compatible valve.
A good example would be this:
I have a 2004 Ford V10 6.8L; it's a motorhome F53 Winnebago.
What valve will fit this engine?
Please keep in mind that we only list cars, trucks and the most popular industrial engines.
If you want a Fumoto Valve for your snow blower, generator, lawn mower, boat, utility vehicle or transmission most likely we will not have any information available.
We strongly recommend you manually measure the diameter and thread pitch of your oil pan drain plug, so we can tell you the corresponding valve size.
Ways to measure:
1) Using Vernier calipers, measure the diameter of the threaded section of the sump plug. This may be all we need to match your sump plug with a valve.
2) The easiest way, take it to a hardware store and mate it with a nut or ask a mechanic to measure it for you.
We apologize for the inconvenience and if you have any other questions feel free to contact us.
