For those of you running an electronic oil pressure sending unit, such as the autometer piece:

How have you plumbed it or attached it to the engine block?

I ask because mine is currently rigged up with some npt fittings and it seems to leak a bit.

I was thinking maybe an npt - AN/JIC fitting, some small braided hose..

any ideas?

The GM style is small enough to simply attach direct to the block.. the autometer is not.

Used a long nipple and a 45° coupler to angle it out in the open area.

Ignore the dust, photo was taken during the body work phase.

I have the Autometer one and even though it looks like it won't fit, it will. I removed the distributor (HEI), doped the threads, screwed it in and reinstalled dizzy. I had already bought that 045* fitting pictured above but didn't need it.

I made mine up with a 2" pipe, a T and a 90 degree so I could still have the dummy light switch still connected. It was a tight fit but I didnt need to remove the distributor.

There's no reason you can't use the braided line, it's just an expensive solution to a simple answer. See if it will fit underneath the distributor first, and if not, look at the 045* fitting. IMHO

Oil Pressure Line


I have used this pressure line for the last 3 years on my Nova. Blue nipple is 1/8" NPT and is easily installed with a 1/2" wrench or socket. Line is approximately 14" long and uses a 9/16"" wrench. The line is long enough to hide behind the brake booster. This particular sending unit has dual electrical connections for both my gauge and light.
Hope this helps.

Yea I agree with CorkyE, and then you'll still have to mount it somewhere secure.

Yup the parts are only a few bucks from Lowes. You will not find a 45* on the shelf tho. Get a straight with a 90*. Just as pictured by Harbone.

The Autometer will not install behind the dist without these parts.
