1999 Sonoma has no carb and the engine runs from a fuel injector (SCFI) and the (FPR) Fuel Pressure Fegulator is located at the injector unit in the upper intake platinum. Here is link to where your fuel pressure regulator is located.

Number 18 is your fuel meter and is where your fuel pressure regulator is located.

Number 13 to 18 is what your going to need if you have to replace the FPR.
