Fuel Filter/Water Separators (Diesel Engines Only); Anti-Siphon Valves (Gas Engines Only) - Bayliner 305 Owner's Manual

305 • Owner's Manual Supplement

Fuel Filter/Water Separators (Diesel Engines Only)

• The frequency of water draining or element replacement is determined by the contamina-
tion level in the fuel.
• Inspect the collection bowls for water daily.
• Replace the elements at least once a year, or when a loss of power is noticed, whichever
comes first.
• Each fuel feed line features a fuel filter/water separator.
• Service instructions for the fuel filter/water separators
are provided on the filters.

Anti-siphon Valves (Gas Engines Only)

• 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 either engine with its anti-siphon valve removed, except in an emergency.
• The anti-siphon valves are vital fuel system parts.
• If a fuel line ruptures, this valve will prevent the fuel from siphoning from the tank.
• The valves are located on the fuel tank, where the fuel feed lines attach to the tank.
• These valves are spring loaded and are opened by fuel pump vacuum.
