(disclaimer it's a Ramcharger but there's a lot more air grabber hoods out there)
OK hood worked ok then switch went bad, I replaced it and it isn't working and it just ain't makin' sense to me. Now before we say "well it's obviously the switch" I'm getting the same vacuum going in as coming out, so I'm stumped

1) Right off the manifold at Idle 18lbs of VAC, if I hook the manifold hose directly to the "open side of the door actuator, it opens right up normally



2) After going through the can, switch, all the hoses and back to the actuator it drops 17lbs and will not open the door, rev it up to 20 lbs and nope still doesn't open


Now I know the basic physics that the hose off the manifold is a big bigger so I have some more volume, but why wouldn't it would the way it's supposed to with the factory hoses???
