Connecting The Fuel Supply - Kohler 26RCA Installation Manual

2.1.3

Connecting the Fuel Supply

The dimension drawing in the Drawings and Diagrams section shows the location of the fuel inlet connection. Have the fuel
supplier install rigid gas piping and a manual fuel shut-off valve. The fuel supply line should line up with the generator set fuel
inlet and end about 12 inches away to allow connection with a section of flexible fuel line. Use flexible sections to prevent fuel
line breakage caused by vibration.
Note:
Do not bend the flexible fuel line to make up for misalignment of the fuel supply line and the generator set fuel inlet.
Apply pipe sealant that is approved for fuel connections. A factory-installed bracket prevents the fuel solenoid valve from turning
when the fuel connections are tightened. Do not place a wrench on the coil at the top of the fuel solenoid valve when tightening
the fuel connections. See Figure 11 for the recommended wrench locations.
Do not use a wrench on the regulator or
fuel solenoid valve in this area

Open the manual fuel valves and test all fuel connections using soapy water. If a leak is found, close the fuel valves, clean the
fittings, and apply fresh sealant. Check for fuel leaks again with the generator set running.
Protect all fuel lines from machinery or equipment contact, adverse weather conditions, and environmental damage.
