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.
EXHAUST SYSTEM
Exhaust system components will vary from one installation to another; therefore a muffler and tailpipe
may not always be furnished with the Genset. However, it is imperative to install a muffler and tailpipe to
reduce exhaust noise and direct exhaust gases beyond the vehicles perimeter and away from the normal head-on
air stream. Install a tail pipe with as few bends as possible to prevent excessive backpressure. A properly
installed exhaust system must be vapor tight, quiet and completely safe for the vehicle, its occupants and
surroundings. Installation of an approved Spark Arrestor is required.
The exhaust system components must be approved and properly installed to meet the codes and
regulations required by Federal and State agencies.
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.
