"How to" request: electronic oil pressure guage install

[livelyjay]

Installations are going to be pretty equal across the board. I think the way I am going to do it will be the best of both worlds.

For Oil Pressure:
Relocation kit (make sure it has threaded hose ends and not barbs)
Male to two female tee (fits hose end from kit)
Male to female adapter (move down size from hose end to 1/8 NPT of oil pressure)

For Oil Temp
The best place to get the temp reading is the oil pan. Autometer makes a special fitting that adapts the oil pan plug, in male size, to 1/8 NPT female for the temp sending unit.

Sry to post this question here but I figure since yall know about install oil pressure gauges, that yall would be able to help me with this. I finally got my gauge installed, and I really dont know how to go about reading the gauge correctly. When driving about 75 to 80 mph, it read about 42 or 45 psi or what ever it units are. (check in the morning.) Anyhow when the car idles, it drops down to like 15 or so.... Does this sound correct. I thought that the gauge was suppose to stay at the same level at all times while the car is running...but I guess I'm wrong.

Also I have to check in the morning to see if I have any leaks, but I didnt have to go through all the work of ordering the fitting off line to make it work with the stock spot for the dummy light. I just went to my local hardware store and took the two pieces that I was trying to connect and they hooked me up with what I needed. (plumbing section of Lowes) So far so good...

It depends on the type of gauge you have, but at idle your oil pressure will be lower and at full throttle it will be higher. It's been a while since I've had a gauge, but I think your readings are a bit low. I think when driving I was seeing close to 100 psi and idle I was around 15-20 psi. Check for leaks. If you don't have any then maybe you don't have a "valid" pressure source.

Yea, I did have a leak, Oil was all over the place. I think I have it fixed. So it is normal to see it move around a little. The spot that I used was the spot where this forum talked about...T'ing off where the Oil Dummy light sensor is.

 

[livelyjay]

That is a valid pressure source. If you did not use the correct fittings, however, you will never solve the leak problem. I hope you used BSPT (British Standard Pipe Thread) fittings for the block and dummy light sending unit, because normal NPT (National Pipe Thread, what the aftermarket gauge sending unit will be) that you'll get from Home Depot will not work and will always leak.
