Hi, anyone know the exact specs of the fittings at the fuel distributor of the 300E where the upper and lower chamber pressure are taken?? I know from memory they are (I think) 10mm, but would like to know the complete spec (thread length and step). I'm trying to get a fuel gauge custom build and I am at this moment not anywhere near my car as I am traveling overseas.

Any help appreciated. Thanks.

-Alex
