oil pressure?
I have installed an aftermarket oil pressure gauge & sender on my 1978 F-100, 302. The engine is a remanfactured engine with about 50T miles on it. I have disconnected the dash gauge. I am running Rotella Triple T 15w-40 oil.
2 questions -
1. What oil pressure should I be showing at idle?
2. Would both dash & aftermarket gauge work if I hooked the wire to the original sender along with the aftermarket gauge wire - or would it damage the gauge and/or the sender?
Thanks,
CB3

Sure, run em both, won't hurt anything.
oil pressures:
Stock oil pump will be 30-50psi cold idle, 10-20hot idle
HV pump will be 65-85psi cold idle, 20 hot idle
HP pump will be 65-85 cold idle, 50 hot idle
I'm sure some will vary, but these are basic guidlines. The engine build/clearances will make up the difference.
