Anyone know the thread size of the oil fill cap on a 7.3 idi? I want to use the neck for my four air out instead of the 3/4" npt bung i welded onto the lemon cover. eliminates basicaly two 90 degree bends and is a larger opening.
Thread size and pitch of oil fill cap?

Dunno but I found a big soda bottle made a funnel that fit the threads.

I don't think it is a standard thread. Molded parts like that typically have like a GL thread that is rounded. See it in glass containers and bottles a lot. If I think of it I'll grab some of my GL plugs here and try them in the filler neck.
