FUEL
CONNECTION
For gasoline sets, connect the fuel line to the fuel
pump inlet. Pump thread is
1/8-27
NPTF.
Connect the set to the fuel source with a flexible line to avoid line
failure due to vibration.
For gaseous sets (see Figure 3) check with the local
fuel supplier for gas regulations and line pressure.
Provide a manual gas shutoff valve. A filter in the line
may be necessary. Electric solenoid shutoff valves in
the supply line are usually required for indoor
automatic or remote starting installations. Connect
solenoid wires to battery ignition circuit (Figure 3) to
open valve during running. Install a demand type gas
regulator according to instructions and position it
near the set to aid starting (regulator line pressure
must be within 2 to 8 ounces).
Always use flexible tubing between engine and the gas demand
regulator.
Gas-Gasoline sets provide a manual shut-off valve in
both fuel supply lines.
