how much boost can the stock fuel system hold?
mine gets cut out at 15 pounds.
Where is the fuel filter? so i can replace it and hopefully solve the fuel problem.

I wouldnt go much over 15 psi with the stock pump, especially if it is old or the original. Only real way to se if the pump cant keep up is to get a fuel pressure gauge with a long enough hose so you can see the gauge while driving. Check to see if FP increases 1:1 with boost at WOT. If it does, you are fine. If pressure levels off, or worse, drops off with boost, you have a problem.... either weak pump, plugged filter or filter sock in tank plugged.

Filter is located under the car.... pass side, near the back of the door.
