INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.
4. REMOVE CHARCOAL CANISTER
5. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
6. CHECK FOR CLOGGED FILTER AND STUCK CHECK
VA LV E
(a) Using low pressure compressed air (4.71 kPa (48 gf/cm
2,
0.68 psi)), blow into port C and check that air flows without
resistance from the other ports.
