I'm getting around to changing the in-tank fuel pump/sock on my 91' 740 turbo sedan. I've had fuel problems for a bit now and I suspect the in tank pump is bad and want to change it out. Long story short, I'm in NY and the car has also been in NY most of it's life so rust on things like this is a problem. I'm looking at the sending unit and trying to wiggle the hoses off and notice the elbows coming off the unit flexing or bending. The unit is covered in rust and I don't have high hopes of getting this out in one re-usable piece so I'm starting to look for a used unit but I have a question. I see some on eBay etc but with straight hose connections instead of the curved "elbow" try my current unit has. Are these straight and elbow units interchangeable or should I try and find one with the bent elbows like whats in the car now? I'll attach some photos of what I'm working with. Thanks in advance!
