oil pressure gauge

I'm trying to install a mechanical oil pressure gauge but am not sure where to tie on my oil feed. Anyway to tie on somewhere near the electrical sending unit for the oil light on the filter housing? Thanks

I believe the best way to do it is to "T" off the back of your pump.
1 of the holes will be for the sender and the other for the oil line.

Or lose the sending unit (just an idiot light)and use that hole.

Theres probably a hole in the block you could use as well. Slant six gurus will probably chime in.
