Just in case anyone's done assuming about TBI fuel pumps as used in a 90
F-Body, at 12v they are rated at 29 gals/hr, or about 180 Lbs per hour.  So
if everything was absolutely perfect (ie 0 restriction fuel filter), the
absolute max would be 360 (or dreaming at .45 BMSC, 390)(also, really hard
to do with TBI), so figure with lines, and the fuel routing (of the F-Body
that I explained b 4). Your out of fuel prolly at 240HP, on it's best day.
Then if you try cranking the pressure up the volume drops even further.
  Course there can be other contibuting factors to why a car doesn't run.

  the above is reference to an EP126 AC Pump..  Just happened to have the
book out.....
