The harness should have shut the pump down...but if the wires were fried....it could keep going but I highly doubt it.
Tim Lenig (his father) told me the pump did get shut off...but that it had already caught the bike and fuel on fire and had been pumping fuel all over the bike before he shut it down...so it was too late.

Ben,
I assume the harness update still uses the stock type setup where the hot side of the pump is always hot, and the relay completes the loop by connecting ground?
Any way to reverse that so it's not always hot? Seems like cutting the positive side would work a little better in situations like this.

A relay for both the positive and the negative would do the job you could control either relay with tether also or a Emergency shut off switch.Probably though only thing to stop this once its started would be a extinguisher system like race cars have.I still wish we had stainless braided fuel lines with crimped ends throughout our quads it would be much safer.

The harness is positive and negative controlled...they key can kill the pump, the ECU can kill the pump...and a properly wired kill will shut the ECU and pump down also. I did this to keep a pump running condition happening, let the ECU still control the pump, and to provide one more means of overriding the pump control to shut it down in an emergency. So to answer your question Jay...it is done that way.
But here is the reasons those things cannot...it you don't have a kill switch or on off switch hooked up or the key switch is bypassed then their are no backups.
