good idea, Eddy, I'm thinking now that a small plumbing type ball valve could be fitted due to the really long pipe the present valve has before it goes thru firewall. I don't care if the cable works it, but inside like you discribe would be no problem to reach under dash and flip.
What type valve that is clear are you talking about?
