wheres the fuel regulator on a 92 PA SC ? i got this hesitation under load and i have changed spark plug wires, plugs, o2 sensor, fuel filter.

i guess the problem is fuel related.

so wheres the fuel regulator?

or does anyone have have an idea?

It's on the fuel rail on the driver side towards the rear of the firewall. It also has a vacuum line that runs from the side of the supercharger and splits between the MAP sensor and pressure regulator.

It might be best if you check the actual pressure before replacing it. The tool is about $45 but a local mechanic may check for free or at least pretty cheap.

Good luck!
