Fuel delivery system
I have a 1991 GMC Sierra that is
having fuel delivery problems.
It'll start fine and run fine until it
warms up, then it seems like the
fuel pump quits working. I've
watched the see through fuel
filter that is close to the
carberator to see if in fact it is a
fuel delivery, and it is in fact a
fuel issue because the filter is
sucked dry by the carb and the
fuel pump seems to quit
pumping, but this is only when
the motor is warmed up
