Considering adding in this $20 item to the electronic fuel pump circuit in my restomod Nomad build...specifically to kill the power to the fuel pump relay in the event of a hard crash, rollover, etc.

As its wired now, if I had an accident that resulted in a break of the fuel line anywhere between the tank and the engine, (with the 12v power still on because the key is on)...I'd be shooting fuel out at the rate of about 50 pounds of pressure. Instant fire I think...

Do any of you guys run something like this item to kill the power to the intank pump and stop it from becoming a flamethrower?
