Section 3 Fuel System

lines attach to the fuel tanks. These valves

help prevent gasoline from siphoning out of

the fuel tank should a line rupture.

All boats equipped with gasoline engines are

required to have anti-siphon valves by the

U.S. Coast Guard.

DO NOT remove anti-siphon valves from

system. Anti-siphon valves prevent fuel from

flowing into bilge should a fuel hose or fitting

leak. If the valve becomes clogged, clean

and reinstall or replace it.

Fuel Tanks

The fuel pick-up tubes are positioned in the

tanks to achieve optimum fuel usage, fuel

line routing, etc. At certain speeds and hull

trim angles, the fuel supply at the withdrawal

tube can increase or decrease accordingly.

Be extremely careful when attempting to

operate the boat when low on fuel. Though

some fuel may be in the tank, the trim angle

of the boat may cause the fuel to flow away

from the pickup tubes.

Fuel Gauge Senders

The fuel gauge senders are more accurate

when the boat is stationary and level.

Because of the change in attitude when the

boat is underway, variations in gauge read-

ings can occur. This system is a relative indi-

cation of the available fuel supply and not a

calibrated instrument.

Fuel Fills

A fuel fill deck plate is located on each gun-

wale and is marked “GAS.” The fuel fill is

opened by turning it counterclockwise with a

special key. After fueling, install the fuel cap

and tighten with the key, DO NOT over

tighten. Use only the fuel recommended by

the outboard manufacturer; refer to the

engine owner’s manual for additional infor-

mation.

If fuel is added to any other tank, DO NOT

attempt to pump fuel out, these systems are

not designed to pump fuel. Fuel must be

removed by qualified personal only. Fuel in

other systems, will also require replacement

of that system and/or many components.

Fuel Vents

There are two fuel vents for the fuel tanks,

one on each side of the hull. While the tank

is being filled, air displaced by the fuel will

escape from the vents. Do not allow fuel to

be expelled from the vents and pollute our

environment. Fill the fuel tanks slowly and

monitor the fuel gauges while filling. Spilled

fuel can be dangerous.

Wash the areas around the fuel fill plates

and below the fuel vents to help reduce dis-

coloration of fiberglass or striping.

Fuel Filters

Fuel filters are located in a locker in the aft

starboard corner of the cockpit. The filters

are the water separator type and there is

one filter for each engine fuel line. Check

both filters for water frequently to ensure an

adequate supply of clean, dry fuel to the

engines. The filter elements should be

changed once a season. Fuel primers are

also built into the top of each fuel filter.
