Need thread size for:

[Diesel911]

Who knows what Is the size (to get a tap for that hole) of the threaded hole at the bottom of the oil filter housing that the oil pressure gauge hose fitting goes into.

It looks like an M11X1.5. That's the size of a tap I was able to thread into that hole but it seemed to bottom out a bit early.

Thanks. Did it look as if there was any taper as I thought it was some type of pipe threads or is it straight?
