Was looking thru the fsm for connection points to the charcoal canister from the 25det manifold to the stock 240 canister but came accrossed the connection point to the stock wastegate.

On page 168 of the FSM it shows how the recirulation valve (bov?) is routed to the intake hose then the wastegate actuator (swing valve controler) vacuum hose is taped inbetween . To my knowledge the waste gate connects to a strong vacuum source. According to the FSM how is that a strong enough vacuum source?

and oyeah does it matter how the canister hoses are routed?

Ok I lied a little. I have 3 good pics of it. And the third pic should answer your first question.

Darius, i decided to replace the stock intake manifold with a greddy, and i am buying coolwhips, and in pic 3 on that first post of yours, that big round hose at the bottom, does that serve a purpose on the greddy intake manifold?
