Gasoline Fuel Filter

Each gasoline engine is equipped with water separator type fuel filter. The filter should be checked frequently

and changed at least annually to assure an adequate supply of clean, dry fuel to the engine. It is recommended

that the filters are inspected after the first 25 hours of use and then serviced as needed. Follow the engine or

filter manufacturer’s instructions for servicing or replacing the fuel filters.

TO REDUCE THE POSSIBILITY OF A FIRE OR EXPLOSION, MAKE SURE ALL ELEC-

TRICAL SWITCHES ARE IN THE “OFF” POSITION BEFORE SERVICING THE FUEL SYS-

TEM.

DO NOT DRAIN ANY FUEL IN THE BILGE. THIS COULD LEAD TO A FIRE OR EXPLO-

SION. CHECK ALL FUEL LINE FITTINGS FOR LEAKS BEFORE AND AFTER STARTING

THE ENGINES FOLLOWING ANY FUEL SYSTEM SERVICE.

CLEAN FUEL IS ESPECIALLY IMPORTANT IN FUEL INJECTED ENGINES, AND THE ENGINE

MANUFACTURER'S RECOMMENDATIONS FOR FUEL FILTER MAINTENANCE MUST BE

FOLLOWED EXACTLY.

3.3 Diesel Engine Fuel System

The diesel fuel system works much like the gas system. The main difference is the diesel system is not equipped

with anti-siphon valves, and there is always a fuel return line for the engine that returns unused fuel to its

respective fuel tank.

Diesel Fuel Filters

The diesel fuel filters are installed in the engine compartment. A shut-off valve is located at the fuel filter.

Check the filters for water before each use.

Water is drained from the filters by placing a cup under the filter and draining through the petcock at the bottom

of the filter until clean fuel flows. The filter element must be changed at least twice a season or more frequently

depending on the quality of the fuel and the hours run. Follow the filter manufacturer's instructions for

cleaning and replacing the filter element. Diesel fuel systems may need to be primed after servicing. Refer

to the engine owner’s manual for information on priming the fuel system.

3.4 Fueling Instructions

FUEL IS VERY FLAMMABLE AND CAN CAUSE A FIRE OR AN EXPLOSION. BE CARE-

FUL WHEN FILLING THE FUEL TANKS. NO SMOKING. NEVER FILL THE TANKS

WHILE THE ENGINES ARE RUNNING. FILL THE FUEL TANKS IN AN OPEN AREA. DO

NOT FILL THE TANKS NEAR OPEN FLAMES.
