Fuel Systems
Gasoline fuel systems used in Ranger boats are designed to meet or exceed the requirements of the U.S. Coast
Guard, the National Marine Manufacturers Association, the EPA, and the American Boat and Yacht Council at the
time of manufacture.
All gasoline fuel systems have been factory inspected and pressure tested in accordance with regulations in
effect at time of manufacture. Additionally, each fuel tank must pass rigid tests and inspections performed by the
fuel tank manufacturer.
A. FUEL FILLS
Fuel fill deck plates are located on the port side deck, and are marked with the fuel pump symbol.
Most models are designed with the pressure relief system shown above. Under certain conditions the system
will be under pressure.
Always open the cap slowly to allow pressure to escape. The vented deck fill is designed to maintain system
pressure below 1 psi.
While filling the tank, the air displaced by the fuel escapes through the fill/vent. See Figure 1.
Periodically inspect the deck fill plate for damage. Be sure to use the exact fuel fill/
vent used on your boat if replacement is required. Excessive pressure or vacuum in the
fuel tank may damage the fuel system, if cap is substituted. (Fuel fill deck plate is not
waterproof; water can be drawn into fuel tank during vent operation, if fill is submerged.)
After fueling, replace the fill cap, and wash the areas around the fuel fill plate, if any
fuel is spilled. Residual fuel left on the deck and hull sides can be dangerous, and will
yellow the fiberglass.
B. FUEL GAUGE
The fuel gauge indicates the amount of fuel in the tank. The fuel level is displayed on the console mounted
gauge when the ignition switch is “on”. On models with two tanks, a console mounted switch marked with a fuel
pump symbol or just “fuel”, is used to switch the gauge from one tank to the other. Push the fuel pump symbol switch
to display the level in tank 1 (starboard) or tank 2 (port). Or, on some models, push the switch to the left to display
the port tank fuel level and push to the right to display the starboard tank fuel level. The center position is “off”.
C. FUEL SENDER(S)
Due to the mechanical nature of the fuel sender, variations in readings during various speeds of operation may
occur. This system is merely a relative indication of the available fuel supply and not a calibrated instrument. With
this type of sending unit a more accurate measurement of fuel level is obtained with the boat in a level position.
D. FUEL VALVE(S)
A fuel hose connects the fuel tank to the engine. On models with more than one tank, a switch valve is installed
to switch from tank to tank. This valve, located at the driver seat, on the panel to the right of the driver, is clearly
marked and easily operated.

DO NOT confuse GAS deck fill plate with WATER or OIL deck fill
plates. Deck fill plates are labeled according to the intended use.
