Don---I am always glad to help out fellow hotrodders, especially when I discover something that has such dire consequences if not addressed properly. I spliced a connection into my coil feed from the switch, and wired in a 1 amp in-line fuse, as recommended by the makers of the solenoid valve.---It was very simple, and I don't have to remember to turn on a seperate switch or open a mechanical valve anywhere. During the summer months, when I use the hotrod as my daily driver, I don't want to have to remember anything except to turn the key to start it and turn it again to shut it off!!!
