Help on this problem with my e36 1st time posting lol
 

So I changed both the fuel pump and fuel level sender. Now I'm getting this annoying whine noise from outside mostly by the right rear . Only when car is turned on and idling. I'm thinking it's the fuel pump but I was sold a tested and working one. Later tonite I'm planning on removing the rear Seat and fuel pump cover and just listen closesly do determine if that's it. . Could it be going bad? Any other suggestions? Thanks

Sounds like the fuel pump to me.

Would that mean its faulty?

It shouldn't be making that much noise, so yes. You shouldn't be able to hear it if the engine is running.

Yea I checked it and it's the fuel pump forsure. Thanks for the help
