Picture of Big Block oil pressure line port for member ts71281

This is a picture of where the BB oil line port is located on my '71 402ci and what the adapter looks like. The adapter is the brass colored piece that the arrow is pointing to.... If you are still not sure what you have, post a picture of the same area of your block in the thread and I can tell you.

Wow! Thanks for posting this! Right now I have a pipe plug in mine that has an allen head :( I just want to make it right :)

I have the guage and she's just waiting on fittings and a line :D

I have a line. All you need to do is go to your Home Depot (or probably any hardware store or home center), get the fitting pictured below, take out the pipe plug and screw this fitting in. The oil line block fitting with my kit will screw directly into it and into the back of your gauge.
