RE: Fuel shut off?
He beat me to it....... look on the Jett FAQ section. Decribes what you want.
Very easy version I use to use........
A piece of .040 wire.... bent in a flat-U shape on the end. Wire exits the firewall, and the U piece returns back into the firewall. Fuel line runs within the loop. Servo pulls the wire and loop toward the firewall, squeezing the fuel line. Works great. You can use DubBro fuel line, or get ahold of thin-wall sonic-tronics or Sullivan fuel tubing. Prather and Aerotrend fuel line will not pinch off quite that easily.
