Hydraulic system problems ('85 5000 turbo)

If the banjo bolts thread into the pump openings and seal properly, you
should have appropriate bolts.  I think the one on the supply line from the
reservoir has a screen in it.  You might check that the screen is clear.  I
assume you replaced the pump with a rebuilt one, but did you rebuild it
yourself or get it from a reliable rebuilder?   Sure sounds like you're
having issues with the pump.  The test for pump output is that you install
a gauge fitting in place of either the hose to the rack or the hose to the
bomb and run the pump up to speed briefly.  You should be seeing 2000+ psi
on the gauge.
