Its on the front of the crankshaft in front of the timing chain.
the oil pump securing bolt is a 7/16-14 thread bolt x 2- 3/8 inch. long. it should be torqued to 60-70- ft. lbs. of torque
50 to 60 psi
$60-$80
60 to 66 psi, engine off, fuel pump running.
Yes, as you rev the engine higher it increases the revolutions of the oil pump which in turn increases the oil preassure. I have a mechanical gauge and it does not spike like that anymore. The electronic sensor is just slow to react.
Assuming this is the 4.3 L engine, 60 to 66 psi with fuel pump running, engine off.
60 to 66 psi
Around 40 psi hot and 50-60 psi cold.
I have a "94" apv. The fuel pump is in the fuel tank and is one of the simpler ones to replace,and reasonably cheep at $60.
With fuel pump running, 60 to 66 psi if it is a 4.3L engine or 41 to 47 psi if it is a 2.2L engine.
60 to 66 psi with engine off, fuel pump running.
40 on idle up to 60 while on the move.
