Can anyone lend me a pre 88 external fuel pump
 

I need to diagnose why my pump is whining. Would be great if someone had an extra laying around (maybe from a parts car) they could lend me to make sure im not dealing with a pre-pump issue, or an FPR issue with my 1987 325is.

I am around the North York/Toronto area.

A buzzing pump or whining pump? you can usually hear it with the car on. the 87 pump I believe is a duel internal and external. Late models changed up.
where do you hear the whining from?

It is a dual pump system. I am 100% sure sound is coming from the external in-line pump, right infront of the back drivers side wheel where the fuel filter is. I am trying to figure out if it is working that hard because the pre-pump in the tank has failed, if the FPR is out of wack, or if it is just the external in line pump that is bad.

Briefly swapping out the external fuel pump would likely answer those questions for me.

OUCH!!! that hurt my ears!! wow that's unusually very loud... can you swing by my place?
Call me if you get a chance in the next 5-10 min..
