Check under driver's side (undercarriage).
Fuel Regulator is probably down there:
- either separate
- part of the fuel filter.

Take the driver side long plastic under body protective cover off [10mm screws and plastic push-in pins] and you will find your 3/2 valve, The Fuel Pressure Regulator is part of the 3/2 valve on your car. There are some safety clips that hold it in like a light bulb for headlights and then there is a tight O-ring pressure fit that seals it to the 3/2 valve body. These are simple diaphram(sp) devices and there should be fuel lines and a vacuum line to the 3/2 valve body.

Buying a new 3/2 valve nets you a new FPR. You can buy the FPR separately. I replaced my 3/2 valve as I had re-newed the entire fuel system (fuel pump, sending units, suction in-tank pump, 3/2 valve and FPR). The 3/2 valve recycles fuel to the tank to keep it cool and the FPR allows 50 psi +/- 2 psi to the fuel rail in the engine compartment to be dispensed through the fuel injectors. If you are having any kind of fuel pressure issues get a fuel pressure gauge with the correct attachment for the BMW shrader valve on the fuel injection rail on top of the motor. Connect it with engine off, start the car and see if you have 50 +/- psi of pressure at the rail. Disconnect the gauge with the engine off and a rag to soak up spilled fuel. Work your way backwards to the 3/2 valve and then to the in-tank fuel pump. The Bentley manual has all the tests and values and tell you how to use a fused jumper in the fuel pump relay socket to see if tank is running / getting juice.
