1) Install a fuel pressure gauge which goes to 100psi between the fuel rail and RRFPR.
2) Start car. Use some blunt pliers and crimp the line between the fuel pressure gauge and RRFPR. Check pressure reaches 100psi and then release. Don't hold it at that pressure long. This checks the fuel pump can reach the needed pressure.
3) The pressures we are looking for are about:
40 psi at idle, 18 inHg vacuum
50 psi at 0 psi boost
75-90 psi at 8 psi boost
Screw the top screw in to get the fuel pressure to increase. You can check the pressure at 0 psi by removing the small hose that goes to the top of the RRFPR. Leave the RRFPR open to atmosphere, and plug the end that goes to the manifold up.
Another person commented, "75-90 psi seems a bit high for 8 psi boost. I think it should be closer to 68 psi."

I started having some trouble with my supercharged BMW E36 318is a few weeks ago. Firstly the car smelt strongly of fuel, and then it started losing power or stalling while driving.

Since I bought this car, the air intake system has been a bit of a mess.

I have a spare 7-button MID from one of the cars I dismantled and now that I have moved to a colder climate (Sydney Blue Mountains) I thought it might be interesting to fit it to see what the outside temperature is.
I am a bit of a 3 series fanatic, having owned a couple of E30s and a few E36s, plus a few parts cars. I like the combination of the compact size, good performance and handling, and that they are more sports sedan than an impractical and extrovert sports car. This blog is a place to share my experience and knowledge.
