Jumping the fuel pump relay?
I did a quick search and didn't really see anything on this specific question. What wires would I need to jump at the relay to run the fuel pump continuously instead of the 5 seconds? I need to pump out the tank and would like to jump it at the relay but don't have a wiring diagram handy. Thanks.

If your relay is wired the same as the circuit shown in the link ; just put 12V on the red wire at relay and that will put power direct to the pump.
