Fuel Fills & Vents
•
The fuel fill fittings are
marked “Diesel” or "Gas".
•
If you experience diffi-
culty filling either fuel
tank, check to see if the
fuel fill hose or vent hose
is kinked or collapsed. If
there are no visible signs
of a problem, contact your
local dealer.
Anti-siphon Valve (Gas Engines Only)
•
Gas fuel systems are equipped with anti-siphon valves.
•
The valves are located at the point where the fuel feed line attaches to the fuel tank.
•
The valve is spring loaded and is opened by fuel pump vacuum.
•
This valve will prevent fuel from siphoning from the tank in the event of a fuel line rupture.

If an engine running problem is diagnosed as fuel starvation, check the anti-siphon valve. If
the valve is stuck or clogged, change or replace it while the engine is shut down.
•
NEVER run the engine with the anti-siphon valve removed, except in an emergency.
