Might be of interest for the Aussies which pay a lot for OEM pumps. In this case it is an E32 740 with M60B40 engine. Here copied the info from Bimmerboard:
"What a difference a new fuel pump makes
The "Beast" died yesterday, usual place, centre of a major intersection, peak hour traffic, great. Towed home, established the pump was not working, now was it not working coz it died, or lost it's signal from the "brain"????????
This stems to my ask recently about the "magic reset", coz every now and then I was getting a slight stumble as I took off from the lights. Then it went away, then this. I really should have picked it, as all my Jags (V12's mainly) have done this just before the pump died, but they are external pumps and easy to "whack" and hear running, or not. The BMW is not so friendly, oh well.
Anyway, I was not paying $400+ for a BMW pump, even aftermarket, and none in SA anyway, so a universal in tank pump was "made" to fit, easy really, and damn the car runs "sweet". I thought it was a sweet V8 before, but this is SWEET. It was the original pump dated 10/1993, so it is fair enough. I might still do that reset one of these days mmmm."

I asked him for details, here the answer:
"OK, here goes.
Used a Goss GE017, which is listed for our Aussie Falcon V8, and as a "universal", and that word is open to interpretation I believe.
Specs are:
51mm diam, internal HP fuel pump.
2.25lpm @ 200kpa drawing 4.5amps. This is I believe a standard lpm @ kpa indicator.
Open pressure 650kpa drawing 7.5amps.
It took a little thinking to secure the pump in the plastic cradle, but a simple hose clamp did the trick, and made it easy to set the depth (I measured that before taking it apart). The sock took some jiggling to sit in the bowl without crimping, but once the angles were sorted it worked fine, a bit of push and shove does wonders.
The pressure side did not come into my equation, coz that is taken care of by the pressure regulator, I think, with the excess returned to the tank, at least it does on the Jags, not really much different to any EFI car, and at 650kpa there is plenty of reserve, and our Aussie Falcon V8 uses heaps more fuel than my V8 ever will.
My fuel pressure gauge has a leaking braided hose, so next time I go to town I will get a new hose and report back the actual goings on with my engine.
It took a few minutes to settle to a decent idle, but maybe the ECU needed to get it's head around the increased fuel available????. The old pump is real sick, worse than any I have seen in 40+ years. "

Hope that helps some of you in Australia
