Default Info on the fuel pump relay location and more........I hope it helps, Good luck!!

"HOTWIRE THE FUEL PUMP
Heinz already removed the passenger's side front carpet and the cover to the relay box. On his cherry 1997, the fuel pump relay is the last one on the bottom right. I unscrewed the one retaining screw that holds the relay tray into the box and slid out the tray slightly. Then I gently popped the COVER off the fuel pump relay with a small flat screw driver and left the relay in place. Then Heinz reconnected the battery. With him watching the homemade banjo fitting and the gas can, I slid a piece of folded over plastic fuel line (unused) In between the gap between the fuel pump relay and the one to its left. This pushed the fuel pump relay points closed and energized the fuel pump. So now, the newly installed fuel tank pump is pumping out the tank...Its all good....until we get to about 1/3 of a tank (we simply reinserted the fuel gauge sender to monitor the level, but did not put the spring loaded cover back on it BTW) Then the fuel flow starts to aerate and spit...This means the pump assembly is not seated properly. So, I pull out the wedge of hose holding the relay closed and the fuel pump stops; disconnect the negative battery cable again; slide out the fuel gauge sender, loosen the foot long retaining bolt which holds the fuel pump assembly to the internal Cup/Baffle until about half an inch of the bolt shaft is showing then rap the head of the bolt down (plastic screwdriver handle and rubber mallet - NO SPARKS PLEASE) to push the baffle down and separate it from the fuel pump housing. Remove the bolt."<ul><li><a href="https://forums.audiworld.com/a8/msgs/134668.phtml">Fuel Pump Replacement tips and tricks</a></li></ul>

Thanks! Power goes to the pump, but no fuel. Looks like I need a new fuel pump.

I can't seem to find where the 1 inch cube is located on my 2001 D2. The part # is 4D0 951 253 and has 372 on the top of the cube.

Thanks for anyone on this board letting me know. John

Default Remove passenger footwell carpet.

Then remove the MDF cover where the floor meets the firewall, kind of tilted. 3 or 4 screws. Behind the cover you will see rows of relays. Read the note excerpted above,"Hotwire the fuel pump" where I explained in great detail how Heinz and I installed his fuel pump and tested for proper installation.
