The fuel supply tank may be installed in any safe,
convenient location. If the tank is installed within the
engine enclosure, provide a vent line to the outside of
the enclosure.
The installation of a fuel filter between the fuel tank
Snd the fuel pump is'recommended. The fuel filter
should be fitted with a shutoff valve and should be
easily accessible for cleaning.

Comply with the following installation requirements:
1.
The.shafts of the engine and the load must be
parallel with each other.
2.
The pulleys of the engine and the load must be in
alignment.
3. Mount.the engine pulleys as close to the engine as
possible.
4.
If the installation permits, belts should run
