Fuel Vent And Fuel Fill - Bayliner DX2000 Owner's Manual

DX2000 / DX2000E · Owner's Manual
Fuel Tank Vent and Fuel Fill
Your boat is equipped with a fuel tank vent which serves as a pressure/vacuum release. Periodically check the
vents to assure that they are not clogged.
The fuel fill deck fitting is marked GAS. If you have problems filling the fuel tank, see if the fuel fill hose or fuel
tank vent hose is kinked or collapsed. If there are no visible signs of a problem, contact your local dealer.
Anti-Siphon Valve
· If an engine running problem is diagnosed as fuel starvation, check the anti-siphon
valve.
· If the valve is stuck or clogged, turn Off the engine and then repair or replace the
valve.
· Except in an emergency, NEVER run the engine without the anti-siphon valve.
The anti-siphon valve is a vital fuel system part.
If the fuel line ruptures, this valve prevents the siphoning of fuel from the tank. The valve is located on the fuel
tank, where the fuel feed line attaches to the tank. The valve is spring loaded and is opened by the fuel pump
vacuum.
Carbon Canister Venting System (If equipped)
Your boat is equipped with a carbon canister. This canister filters all the hydrocarbons that pass through the
canister. If the carbon canister is mounted in the engine compartment, the canister will have a heat shield.
Periodically check that the shield has not become damaged.
Fuel Recommendations
The quality of the fuel is very important for satisfactory engine performance and long engine life. Care should be
taken to select fuels having the octane rating recommended for the engine, as indicated in the owner's manual,
for proper operation. Fuel should be clean and free of contamination. Your fuel tanks should be kept full of fuel
whenever possible. This will reduce the amount of water condensation and reduce the possibility of
contamination.
When filling the tank, do NOT attempt to top off the tank. When the fill nozzle shuts off, the tank is full.
Continuing to fill past the fuel fill shut off will cause the system to spit back.
