Close but not quite. The Evap Canister Vent Solenoid is a smaller valve in the back of the truck at the carbon canister.
The larger one in Tim's picture near the master cylinder is the Evap Canister Purge Valve
. Just to keep everyone confused, some Ford literature refers to the ECPV as the VMV (Vapor Management Valve).
The large and the small vacuum lines both go to manifold vacuum but obviously to different ports.
