Fuel pump dead?

Pinching the line does not change it. Initially, as I was attaching the test hose to the test valve, I saw a bit of fuel coming out. But then at the end, when I removed the test hose, I pressed the pin on the valve and there was no fuel coming out at all. Does this confirm a bad pump? Or could it be the pressure regulator inside the filter? Or anything else?


There is definitely no sound (ever). I was just hoping that it could be the filter only... I already got the fuel filter about 6 months ago from TheBMWpartstore as I was planning some preventive maintenance. I believe that they have the best price for the fuel pump too (part# 16116768357 is $272.41). I get all my parts from there unless the local dealer matches the price. I've seen various auctions on eBay, but who knows how 'genuine' those are.


I agree that it is an easy fix and have no problems replacing it (I will replace the filter too), as I do most of repairs on the car. I was just hoping to avoid the $300 part cost

Just buy a universal Bosch fuel pump from HK. Less than 40 bucks and you can't beat the shipping cost.
