Thanks for the information, you saved me some grief with the ground wire. How much gas does it take for this test? My tank was almost empty and I have added one gallon of gas. The blinking low gas indicator still blinks.The 3 wires to the connector are basically: fuel pump live / positive, fuel pump ground / negative / earth and the fuel gauge.
Unfortunatelythe closest wiring diagram that I have reference to, is that of a K5 Vee which is not very clear when I zoom in on this diagram. FWIW, have a look at the wiring diagram in reply #18 of dl 1000 issue., which should give you an idea of the wire colors. Looking at the linked diagram, roughly at middle top, you should find the fuel pump connector (3 wires). Note there is also another connector labeled fuel pump relay (4 wires), but that isn't the connector that you are looking for.
Having separated the fuel tank connector, as Rolex has pointed out, you now need to provide both the pos and neg feeds to the now loose connector of the fuel tank. This will allow the fuel pump to run. You need to control the duration of the connection or the pump will be active while connected in this manner.
