Thanks a lot terry for the pictures. what year is yours? I'm thinking 1981 and later seem to be a bit different to 1980 model. even my heater motor and wiring is different to later models. mine had the transistor built into it.
I've got one line going from the canister to the tank. second hose goes to a T piece near the dizzy and a third hose going to the rear of the manifold.
I'm thinking 1980 and earlier doesn't have the a/c T piece and 1981 and later has???? could be wrong tho?
