Aftermarket oil pressure senders suck!
I knew I should have gotten an OEM like every sensor I replaced in my engine.
I used to have a little over 20psi scolding hot idle in the middle of summer with shitty oil and a stock pressure oil pump.
After replacing the sending unit which seemed to give false readying because the needle kept going up and down a little, I made the mistake of getting some brand off Summit, which is also acting the same way at hot idle.
I also just installed a standard volume high pressure pump, and I have fresh 20w50 Castrol in the engine. Cold idle is great, about 50-60psi. Hot idle? Just below the 20psi line :S
Of course when driving, its at 40psi, goes more at WOT.

Hey:
I don't remember seeing an Advance Auto when I was in Bahrain, just do a NAPA one, thru internet/mail order if you can't get an OEM, they are as good or better than stock GM supposedly.

However, the needle wandering on its own only means I cannot rely on the sending units accuracy. I guess having an accurate reading is always better. But having a reading is also better than none lol

Is it a mechanincal gauge? If so I just put a T fitting inbetween the block and the oil pressure sensor, and with the other port on the T thats where I ran my oil line for my mechanical oil pressure gauge.

It's electrical. I was searching around and seen earlier lt1's had the oil pressure gauge above the oil filter. Wondering if I could put the autometer one there?

Ya, that should work out fine for you. I'm not sure on what degree elbow you will need as I dont know how big the autometer unit is but thats pretty easy to figure out. sounds like you've already got that part figure out anyway.

Going with a 45deg fitting. Now just going to have to use my buddie's honda size hands to get in there lol. Stupid question, but here it goes. Would I be able to take that plug out and put in the fitting without oil gushing out? Or should I just drain it first, reason being just did an oil change. Be a waste of 20 bucks or so.
