1993 Saturn SC1 fuel pressure regulator

It's built into the throttle body assembly.

Just to add to this one its not built into the throttle body it can be replaced its under call out number 7 in the diagram. Back it the day it only came in the rebuilding kit from the dealer thats the only way it came. But now I think I saw it sold separately I think I saw it on rock auto dot com if memory serves correctly. It might be sold else where you can use the part number from rock auto to help you find a new one. Whats wrong with yours is it leaking gas externally? I have seen that happen before.

Also while your in there make sure you tighten up those two torx screws on the top of the air horn and also two ten studs that hold the throttle body on. They loosen up over time.
