Manual Description
C Each control unit transmits/receives data but selectively reads required data only. Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically. Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
When a stick is inserted, the valve should open, when removing stick it should close. Connect a spare fuel hose, one side to fuel gauge retainer where the hose was removed and the other C side to a fuel container. In this process the air I passes through the hose connecting air inlet tubes to rocker cover.
Under full-throttle condition, the manifold vacuum is insufficient to draw the blow-by flow through the valve. On vehicles with an excessively high blow-by, the valve does not J meet the requirement. A strong vacuum should be felt immediately when a finger is placed over valve inlet.
