So you might keep blowing pumps if you still have a restriction.

Change the fuel filter.

Check that the tank is not building up vacuum from a bad vent valve, (listen for hissing when cap opened).

Put a meter on the fuel rail and make sure it is not too high from a bad regulator or return valve.



The pump you showed was an OEM by VDO so is an exact replacement. If the fuel gauge is not showing right, I suspect either you did not plug it in right, the gauge is bad, or there is a bad ground to the tank unit. Check the ground connection to the chassis for the pump, because it won't work right with a bad or corroded ground.1992 BMW 325is car problems?The pump may be defective (since the sender is likely built in to it. It sounds as if your burnt out pump was the result of a clogged fuel filter however.1992 BMW 325is car problems?I would really call the company that makes the fuel pump, if you can't get any help there. You need to take your car to a BMW certified repair shop and fork out the extra cash for them to fix it.1992 BMW 325is car problems?i would change the fuel filter if that dont help have the fuel pressure checked almost any mechanic can do this rather cheap takes maybe 20 minutes your Friend probably didnt get the fuel sending unit hooked back up you may have to drop the tank again also good idea to change the pick up filter in the tank hope this help and good luck
