putting a aftermarket oil pressure gauge

[Ricks1971]

Looking for a little help? I am putting a aftermarket oil pressure gauge and need to know what fitting you guys use to connect them behind the block?

The kits come with everything you need to install the gage . Don’t use the supplied plastic tubing buy the copper . I just put one in my 72 on the new motor

I went with an electric pressure gauge because I didn’t want an oil line, copper or not, inside the cab.
Here are some screen shots of what I had posted.

I am still going to run the stock one in the dash cluster and going to use a under dash autometer oil and temp gauge. Going to use the same spot on the back of the block but need a fitting that has 2 outlets?

You'll probably have to use a TEE with a short pipe nipple.

Or use another oil port . The one under the distributor isn’t easy to access. I used the one on the front over the timing cover for the stock electric unit on my 85 . It already had a mechanical hooked up under the distributor. There is also a port just above the oil filter boss on most Chevy v8s . Both would be a lot easier to access if you’re running two . I made a bracket for the sender so it didn’t vibrate . No leaks after three years

The oil pressure port behind the intake manifold is 1/8" NPT.

Lots of tee fittings to choose from: https://www.amazon.com/s?k=1%2F8+npt+tee+fitting

You may also need a section of straight pipe to raise the tee.

Not all blocks have an oil pressure port above the timing chain cover, but most have a port just above the oil filter.

OP, if its a SBC there should be a NPT plug above oil filter you can use for the electronic sender. Some headers can be a conflict with that port.

To maintain the stock sender but use that same port, a combo of 1/8 NPT fittings to allow both senders to occupy that space. Due to headers, I had to come up with a combination for this and also clear the coil mounted on my intake manifold. straight, 90 and 45 degree fittings are available on Amazon and some auto part stores

I have to add this about the plastic line. I was driving my 73 Firebird yesterday and the plastic line split and by the time I got to a place I could stop there was oil in my boot, on my pants, and all over the windshield and dash. The line was probably 6 years old.

I'm changing out for a wired pressure sensor...

Good luck, Rg

Never use the plastic tubing you’re just looking for trouble. Pretty sure most of the trucks that have mechanical factory gages still have the original copper lines .

It’s against building code here to use plastic tubing going to the fridge for the water and ice . That should tell you something

Yes, my original line and gauge worked without leaks for 44 years, When I replaced it with an electric sender and gauge, there were signs of a slight oil leak in the gauge fitting, but not even enough to form a drop.
