#### INSPECTION AND SERVICE

Check the hoses for proper connections and damage. Replace as necessary. Check the vapor separator tank for fuel leaks, distortion and dents, and replace as necessary.

##### Carbon Canister and Purge Control Valve

To check the operation of the carbon canister purge control valve, disconnect the rubber hose between the canister control valve and the T-fitting, at the T-fitting. Apply vacuum to the hose leading to the control valve. The vacuum condition should be maintained indefinitely. If the control valve leaks, remove the top cover of the valve and check for a dislocated or cracked diaphragm. If the diaphragm is damaged, a repair kit containing a new diaphragm, retainer, and spring is available and should be installed or replace the carbon canister assembly.
