Title: Fuel Pump wiring harness '03 M620
Post by: 808Ducati on July 02, 2013, 10:36:45 AM
4 wires into the fuel pump wiring harness on the tank - two black, one red and one white.  Which two are for the pump itself?  My pump is dead and I want to send power to it directly from the battery to ensure that it's not something in between.  Will test at harness and if that doesn't work will have to pull it and test at the pump itself to ensure it's not the wiring a the tank flange.  Also, anyone ever bought one of these $40 pumps off of eBay:

The large red and large white wires, positions 1 and 2 on the plug, go to the pump.

Haven't heard of or used that EBay pump.

Those clamps aren't very good, and I'd bet that bit of hose isn't immersion rated 30R10 hose.
