Check Fuel Pressure
1. Check fuel pressure at the regulator in the
generator by following these steps.
• Close fuel supply valve.
• Remove the top fuel pressure test port from the
regulator (see Figure 5-4) and install the fuel
pressure tester (manometer).
• Open the fuel supply valve and verify the pressure
is within the specified values.
• Record static fuel pressure:
NOTE: Fuel pressure can also be tested at the
manometer port on the fuel shut-off valve shown in
Figure 5-2.
NOTE: See the Fuel Data Decal or spec sheet for proper
fuel pressure specifications. If fuel pressure is not within
specifications, contact the local fuel supplier.
2. Close fuel valve when completed, but keep
manometer connected for future tests of the
generator while starting, running, and under loads.

Perform Leak Test
All products are tested at the factory before shipping to
ensure the performance and integrity of the fuel system.
However, it is important to perform a final fuel system
leak test before starting the generator. The entire fuel
system should be tested from supply to regulator.
See Figure 5-5. Perform a final fuel system leak test
after generator installation. The test will identify possible
leaks at all connection points (A).
It is best practice to perform a fuel system leak test during
normally-scheduled maintenance.
Figure 5-5. Connection Points to Leak Check
Check for leaks by spraying all connection points with a
non-corrosive gas leak detection fluid. The solution should
not be blown away or form bubbles.

DANGER
Explosion and fire. Fuel and vapors are extremely
flammable and explosive. No leakage of fuel is
permitted. Keep fire and spark away. Failure to do
so will result in death or serious injury.
