I'm going to give the same answer I gave in your other thread on this subject:

What you can use should be listed in one of these threads:

walbro F20000169 is an easy install and low cost and works great

BTW, how does the OP know he needs a new fuel pump and filter?

I'm debugging lean codes and wondering myself:
- Just curious: Does the ORDER of pcodes listed in an OBDII scanner actually matter?

I'm tempted to rent the $150 Autozone fuel system tester (if it works for our vehicles) to see what that tells me:
- How do I test fuel pressure?

Did the OP do debugging or is it just a standard maintenance thing?

Well, I suspect fuel delivery issues, plus the car is at a mileage where I am doing it as a matter of prevention. I would not want it to go out on me somewhere and leave me stranded. Bluebee, what is the tester that you are referring to from autozone.

I replaced mine as I am in the process of doing the supercharger install, but wow I didn't even realize mine was on the way out. Much smoother throttle response and the walbro is way quieter then mine. I was used to the old one and I guess I didn't know the noise I was hearing was a sign. MIne never gave out, but I would not like that to happen. It is a good feeling knowing that it is new and fixed a problem I didn't know I had. For about $100 it is a great preventative item

Stop by your local AutoZone, and ask to see it. The V8 has no Schrader valve on the rail. You need a kit with quick-change fittings to tee into the fuel line.

I also saw one at Harbor Freight that might work. IIRC, it was $180.

depends on the year. My 2001 has the Schrader valve on the rail.

Interesting, that is the first I have heard of a 540i with such valve. I know for sure that my 97 DOES NOT have one. I also need some recommendations for the best fuel filter.
Thanks

Here is a reference to the free Autozone fuel system testing kit:
- How do I test fuel pressure on 540i m62 V8?

Actron's Fuel Pump Diagnostic Kit, No.CP9220A, is designed to help detect whether a fuel pump is defective and to assist in diagnosing fuel-system related performance problems. This kit features a 40" gauge hose to easily reach any test point. The kit is compatible with vehicles that have a Schrader valve test port on the fuel rail; a detachable rubber hose connection at fuel rail, fuel line or fuel filter; are GM models with threaded connection at fuel filter or throttle body; or are Asian, European and domestic makes with a "banjo bolt" connection.

And, here's a picture of the M54 engine fuel supply Schrader valve:
