fuel pump relay - shorting it out to empty tank

[fergus]

Quick q, w/o the manual, does anyone know which relay in the MFRU is the fuel pump one? I need to know where it is in the unit and which pins to short to get the fuel pump to run constantly, as I need to drain my tank tonight!

thanks in advance.

You should have a relay box probably on top of the ECU. Either disconnect it and put 12v to the green and yellow wire (looks a bit like a domestic earth cable, you can put a male spade conector into the multiplug) or If you have a peircing cable tester earth the purple and black with it all connected and the ignition on

Was that easy enough? I had my battery out of the car so just connected it to the plug directly.

I used Ben's solution by shorting the green/yellow pin (+12v fuel pump feed from the MFRU) direct to the battery.

Amazing how long it takes for the tank to drain!

cheers all.
