80stech and andrewwynne: As I'm probably going to order a new aftermarket fuel pump for my '01 X5 pretty soon https://xoutpost.com/bmw-sav-forums/...inspected.html (after I further test mine outside the tank...if it's possible that the pump won't run if the fuel filter is completely clogged, then I have to investigate it); this thread has made it seem impossible to choose a pump, since I don't know if I'll have to adapt one brand of pump to fit into the holder or not, and it looks like nobody has a go-to pump they'd recommend. Plus, since mine is a 7/2001 build, has anyone ever changed out a pre-facelift pump?

Off-hand, I would've assumed that Hella and Pierburg would be OK for BMW's, and since I've been mainly a General Motors afficionado for 60 years, the AC Delco (and the modern Delphi brand) have positive connotations to me.

Whatever pump I order, I sure don't want to have to pull it out immediately due to some unforesaaen failure, nor do I want to have to re-engineer a pump to fit in my X (I've done WAY too much redneck engineering in my day...I want a plug & play solution the first time). Talk to me about this, please!
