The old rule of thumb used to be 10 lbs per 1000 rpms. So, if that old Chevy small block engine is warmed up and idling with 10 lbs of oil pressure, don't worry about it.
The 4.3L engine in 2002 should have 60 to 66 psi of fuel pressure.
92
6psi(41kpa) @1000rpm, 18psi(124kpa)@2000rpm
50 PSI, nominal.
== ==
4-7 lbs. if it has a carburetor.
It should have 9 to 13 LBS of fuel pressure. No higher are lower, are you will have starting and running problems.
Around 3300-3400 lbs.
9 to 13 LBS. It CAN'T be any LOWER are HIGHER It must be within that area.
