INSPECTION
•Gasoline is extremely flammable and is explosive
under certain conditions.
● Keep flames and sparks away from gasoline and wipe
up spilled gasoline at once.
•Be sure to remove the diaphragms from the fuel auto
valve before using compressed air to blow out the air
passages. Compressed air wil damage the
diaphragms or may force them off the aluminum
link.
● Disconnect the fuel line and place it in a clean
container as shown.
•Place a clean container under the fuel tube.
● Connect the fuel auto valve vacuum tube to the
vacuum pump and apply vacuum. Be sure that the fuel
flows out smoothly. If the vacuum does not remain
steady, it indicates the diaphragm is incorrectly
installed or damaged. If the vacuum remains steady, but
the fuel flow is not smooth, it indicates a clogged filter
or incorrectly installed diaphragm.
● If the fuel flows without the vacuum applied, the
diaphragm is incorrectly installed.
