Have a 1997 GMC half ton. Has the 350 vortec in it. Fuel pump died
while driving it. Towed home. Did the old dump bed trick to change
the fuel pump. pull 6 bolts and loosen the 2 close to the tailgate and
lift the bed up from the front. Easy acces to the pump.
Now, it stutters. And is running rich. Also shifts a little funny.
It ran perfect before. All vacume lines are hooked up. No leaks.
Changed fuel filter and pickup screen too. But, nothing got in the
lines anyway. Or in the tank.
