The vacuum lines run from the canister to the intake manifold. One is the purge hose to deliver stored fuel vapor to the intake to be burnd when engine is warm and you are crusing at part throttle. The other line is the vacuum line to operate it.
Fuel Vapor Valve, Aerostar (4.0L Engine)
The evaporative emission valve (9B593) uses a small orifice, 1.83mm (0.072 inch), that allows vapors to pass into the vapor line running forward to the evaporative emissions canister (EVAP canister) (9D653). This evaporative emission valve mounts directly into the fuel tank (9002) using a fuel vapor separator seal. Fuel vapors trapped in the sealed fuel tank are vented through the orificed evaporative emission valve. The vapors from the fuel tank leave the evaporative emission valve through a single vapor line and continue to the evaporative emissions canister in the engine compartment for storage.
