fuel pressure ??
What fuel pressure should my 90 LB9 run at? I stuck a gauge on it and the guage shows around 35 to 36. What should I be looking for? Thanks

Could be right.

Should be at 44-45 with the vacuum line disconnected.

There's no 'ideal' fuel pressure setting that works on all cars. I would leave it alone, SD cars tend to run rich anyway.

Why the concern for pressure? Do you have a specific problem that you think may be related?
