So just to clarify Harold, your valve isn't actually mounted to
the firewall, it's just close to it with a short section of hose?

Thought this would be obvious, but yes, the outer sheath of the
cable has to be mounted solid in relation to the valve bellcrank,
just as it is with the choke, throttle or defroster cables,
that's the whole principle behind the way a push/pull control
cable operates.
