You guys are crazy.
Just don't hit that switch as you go around the corner. Know someone who hit the switch whilst the engine wasn't running.
Now that makes for even more fun - engine rebuilding.
Perhaps direct into manifold via fogger ( 8 of ) looks better. Solenoids mounted at back of manifold. Would consider a purge line exiting from the scoop for special effect. Looks great at night with a big foggy mist shooting high in the air. Little gas used doing this.
For interest it is an offence to have a filled bottle in a car (connected) here in Australia.
Cheers - have fun..
