Engine/Transmission (1998.5 - 2002) lift pump and oil pressure numbers

[tmarti96]

I have 98. 5, stock at this point, and curious about acceptable lift pump pressures, at idle and cruise at 60 mph. Also, what is normal oil pressure, also at idle and 60 mph. thanks to all.

I would guess my FP is 14 at idle, 11-12 cruising, pretty new pump. As for oil, That guage is less accurate, but I would guess 30-40 idle, and 60-70 cruise. I think it depends some on the oil and filter you are using.
