42C System Operations - 37
FUEL SYSTEM
Fuel, especially gasoline, is extremely
fl ammable. Failure to follow these rec-
ommendations and the rules of good
common sense could result in fi re or
explosion, which could cause personal
injury or death.
The purpose of the Fuel System is to
maintain the necessary supply of fuel to
the engines and generator upon demand
and as needed. The fuel system on your
42C is comprised of the following compo-
nents, which will be described separately:
• Fuel Tanks
• Fuel Tank Fills and Vents
• Fuel Tank Grounding System
• Fuel Distribution Hoses
• Fuel Supply Valves
• Fuel Filtration
• Generator Fuel Selector Valve
• Fuel Gauge and Selector Switch
Fuel Tanks
Your 42C is equipped with two (2) fuel
tanks, each having a capacity of 262 gal-
lons, for a total fuel capacity of 524 gal-
lons. The photo above shows the port side
fuel tank. The starboard side fuel tank is
in the same location but on the starboard
side. Both fuel tanks are located in the Aft
Bilge and access is through the Aft Hatch
in the cockpit. One tank is located on the
port side and one tank is located on the
starboard side. See the Mechanical Sche-
matic in the SCHEMATICS Section of this
owners Manual. The port side fuel tank
supplies fuel to the port engine and the
starboard fuel tank supplies the starboard
engine. Either tank can supply the genera-
tor, if so equipped.
Each fuel tank is equipped with a Fuel
Level Sending Unit, which provides an
electrical signal to the fuel gauge to indi-
cate the fuel level. The photo below shows
the sending unit on the fuel tank.
The Fuel Tanks should be inspected for
signs of leaks, corrosion, and/or pitting
at least once a year. Corrosion normally
appears as a white chalky, discolored, or
fl
aky appearance on the surface of the
tank. Sometimes it also appears as pit-
ting or small pockets of missing aluminum.
Another indication of corrosion could be
bubbles on the paint that coats the fuel
