i have an 02' f-body that has been reading low for years. i would like to hook up a mechanical oil pressure gauge in the engine bay right above the oil filter to see what the true pressure reading is before changing out the sending unit. does anyone sell a kit for this or know what fitting size i would need to hook into the block above the oil filter?

 

I mounted one there for my initial fire-up. It's in a C5 "block" that has the port (temp sender?) in it, but I did have to re-drill & tap to a pipe size. Can't remember if it was 1/8" or 1/4" though. Mine cleared everything by inches, so I left it in place for good.

 

tks, meant to post under gen III
