SYSTEMS CONNECTION
FUEL SYSTEM
The diesel fuel system for the generator set must be designed to operate independently from the
vehicles main engine if both engines are to be operated at the same time. The best way to do this is to
have separate fuel tanks, but this is usually impractical because of space restrictions. In most
installations both engines operate from a common fuel tank with separate pick-up tubes for each
engine, not a Tee fitting arrangement. This prevents either or both engines from being starved for fuel.
The generator set fuel pick-up tube is generally shorter than the vehicles; therefore fuel may not be
available to the generator when fuel supply is low. This will prevent the generator from depleting the
fuel supply needed by the main engine.
NOTE:
Using a simple Tee fitting to supply both engines from a common fuel line is not
recommended. This practice may possible cause a fuel starvation situation to either or both engines.
Also, if excessive pressure were to build up in the main supply line it could possible cause a failure of
the generators fuel lines or connectors and a hazardous fuel leak may occur.
Care must be taken when routing the fuel line from the main tank to the generator set. Keep the
fuel line as short as possible while maintaining adequate clearance from the exhaust system. Fuel lines
must be run along the frame side rails or coach under carriage. Never run fuel lines inside of the coach.
Securely fasten the fuel lines with hardware that is recommended for the type of fuel line used. The
fuel lines should enter the generator compartment at a point nearest to the generators fuel line
connection fittings. Allow for a minimum of 8inches of flexible fuel line to make the connection. Use
proper size fuel line to accommodate the fuel flow needed. Steel fuel line or high quality fuel hose is
recommended, either one should have a minimum of ¼” ID and strong enough to withstand road and
climatic conditions. A positive fuel shut-off valve should be located between the fuel tank and fuel
connection on the generator.
EXHAUST SYSTEM
Exhaust system components installed on a RV Genset must be approved and properly installed to
meet the codes and regulations required by Federal and State agencies. Exhaust Mufflers and Spark
Arrestors supplied by Power Technology meet the codes and standard requirements set forth by the
USDA Forest Service. Laws pertaining to application and maintenance of a Spark Arrestor may vary
depending on your location and State regulations. Federal laws apply on Federal lands. If a generator
is used in a forest, on brush or grass covered unimproved land it must be equipped with a Spark
Arrestor. It is the responsibility of the vehicle owner or operator to install and maintain the entire
exhaust system in good working condition.
CAUTION:
Any person (s) who installs an unapproved Muffler, Spark Arrestor or other exhaust
system component, and/or modifies an exhaust system or component that may result in a hazardous
condition is liable for damages, injuries or warranty expense caused by such unapproved installation
and/or modification.
