Anti-Siphon Valve Test
Remove anti-siphon valve from fuel tank. Install
adapter fittings and a 36 in. (91.4 cm) length of
clear hose to the inlet side (tank end) of valve.
Fill clear hose with water to a height of 20 in. (500
mm). Water must NOT flow through valve. An
occasional drip is acceptable. Replace valve if
water drips continuously.
Increase height of water to 25 in. (630 mm). Water
should flow through valve as water level reaches
25 in. (630 mm). Replace the anti-siphon valve if
test results are different.

WARNING
Gasoline is extremely flammable and
highly explosive under certain conditions.
Use caution when working on any part of
the fuel system.
Protect against hazardous fuel spray.
Before starting any fuel system service,
carefully relieve fuel system pressure.
Refer to Relieving Fuel System Pressure.
Always disconnect the battery cables at
the battery before servicing the fuel sys-
tem unless instructed to do otherwise.
Always work in a well ventilated area and
wipe off any fuel spillage.
DO NOT smoke and make certain no open
flames or ignition sources exist.
After servicing the fuel system check for
leaks. Failure to check for fuel leakage
could allow a leak to go undetected,
resulting in fire or explosion.
