Fuel running with key on,engine off,solution.

[Thrusted Vector]

Here's what we did.Brown wire from ignition to a bosch relay,red wire from pump to relay,then run a wire from the blue/red wire stripe at the fuse box to the relay,one more to ground and viola,the pump doesn't start running till the tail lights come on.We went one step further and hooked a toggle switch between the red and the brown wire to override the relay if you run out of fuel or to prime the system.

On mine I just used the solid blue wire from main relay to turn on/off my fuel pump relay, Thanks Mr. Ryan. Works much better when the sled is rolled, no more intercooler full of fuel
