Default Racetronix Hotwire to Empty Out Old Fuel

Hey guys, I need to empty my tank of old gas and I came across a post by saying it's possible to do this easily by hot-wiring the Racetronix wire kit to activate the fuel pump and pump out the old gas. Anyone know how to do this with the Racetronix kit?

Thanks in advance.

if you have HP Tuners, just turn on your pump through the scanner

Why not disconnect a fuel line and turn the key to the on position?? The pump will just keep running because it can't pressure up the system

Pretty sure that won't work; the system is set to prime for a few seconds, then shuts off if there's no start.
Can confirm, there have been plenty of times where I had a fuel line off, and someone else turned the key on or reconnected the battery, and it'll spay for a few seconds and stop.

One time I got sprayed right in the chest this way...

Because that's an aftermarket setup, not factory.

There is a way to do it on a stock setup, I just can't remember

unplug the relay, run a jumper wire from 30 to 87 on connector. You are jumping power from the battery power 30, to the fuel pump power wire 87. Just use the same gauge wire for a jumper that's on harness.

pump will run continuously and you don't need the key on either.
