FI pressure blues-long and droning...


My car doesn't work.

1970 fastback with 1971 FI, complete.  All parts just swapped from
perfect runing car, including all but one hose.

Wouldn't start.  Un-swapped hose broke. lesson learned for the lazy.

new hose, still wont start.  1 year old line from Pump to car, pressure
side, blisters.  Replace it.

Won't start.  Undo hose right at fuel rail right past the regulator.
Nuttin but drips .  Ah-ha.

Drop engine (Its easier) and undo regulator.  Put extension of fuel
line, wire the pump to run.  Streams out rather nicely.

Regulator. hmm.  Same test throught the regulator, just drips.

play with the adjustment, just drips.

Hmm. Maybe fuel pressure not good enough.  get air compressor.  adjust
it to 60 psi.  Hook it up to regulator.  barely a hiss.

Is my regulator shot?  Is air pressure the same as fuel pressure? Was
that a valid test?  Anyone have a spare?  Augh! Did the check valve on
the pump get stuck???
