DIESEL SYSTEM

Diesel engines use many fuel system components which
are similar to gasoline systems. The major difference in
the two systems is that with diesel you do not have the
vapor and therefore the explosive characteristics of the
gas system. Diesel systems use return lines which send back
unused fuel to the tank for reuse.

DIESEL FILTERS

Many vessels use a special filter that separates water from
diesel fuel and holds it in the bottom of the fuel filter.
Normally these fuel filters feature a drain plug that can be
loosened and drained to eliminate the impurities. Be sure
to dispose of these materials properly. Unlike gas filters
these filters use a glass bowl that can be visually inspected
on a periodic maintenance schedule.

Monitor the fuel gauges and continue to transfer fuel until
the tanks are equalized.
A fuel transfer pump is
included within the diesel
fuel system. The pump
equalizes the volume of fuel
between the two fuel tanks.
The pump is located in the
bilge at the forward engine
bulkhead. The fuel transfer
pump switch is located near
the helm seat or dash area.
