RE: JET LEGEND VIPER BUILD THREAD
Hi Matt,
I'm setting up a VT80 which is the same setup as you describe. I'm going to use a battle axe kill switch which cuts power to the pump so the fuel feed is stopped. I also saw in the T45 thread that Michael used a servo to shut off the ball valve to the engine which complies with our rules and regs.
I got the switch from jetproductsaustralia ( Phil Celima )
Hope this helps
Cheers
Jeremy
