Fuel Pump noise, finally gone, can I stop being worried or?

I have changed multiple fuel pumps in a short amount of time, as they eventually had the whine of death. I then came to the conclusion that there must be rust sentiments on the bottom of the tank, so I bought a new tank, new fuel pump, new fuel filter. Got them all installed, all should be good now.

Nope, this is a BMW e30 after all, it is never good.

After I got the new tank, pump, and filter installed. The whining was still there. Ahhhhhh!

My mechanic did a test to cancel the activity of the fuel supply pump in the tank to take that out of the equation. When he did that, the external pump was as quiet as can be.

My mechanic then took my old pump from the tank to inspect it. The bottom where the screen is, it was brown (rust brown). He took it apart, so he can clean the inside of the screen. It looked like he made a hole as well in the screen (errr), hopefully the hole in the screen doesn't have any long-term issues. After he reinstalled the in-tank pump, the exterior pump is quiet as a mouse.

Since it seems he installed the in tank pump with rust sediments on the screen to my brand new fuel tank, and I drove around like that for a few hundred miles.

Is there concern that some of the rust sediments fell off of the screen from my in-tank pump,and into my new tank, which will then undue the whole process for my reasoning to change the tank to begin with?

Yes, your mechanic made a poor choice. Not only are screens typically available, but they should have just replaced the lift pump when doing the new tank.

I'd say a fair shake is to have them replace the whole lift pump on their dime both P&L.

I am not as concern about getting something out of him, though I do appreciate your comment.

I am more concern about additional issues popping back up, since he did not change the in-tank pump originally after changing the tank, and only now we notice the rust sediments stuck on the screen which he just cleaned off.

1) Should I be concern that there is rust floating around my new tank that could have fallen off the pump screen into my new tank?

Yes, I am saying it's a concern, and to replace the pump/sock.

You mentioned the following:
"Not only are screens typically available"

Do you know where I can purchase just the screen? I am having difficulty just locating the screen for the E30 for cars up-to 9/87
