Checking Fuel Line Connections
Checking Fuel Pressure
Proceed as follows to check fuel pressure at fuel solenoid
valve in the generator.
1. Close fuel supply valve.
2. See
Figure
5-3. Remove inlet side fuel pressure
test port from fuel solenoid valve and install fuel
pressure tester (manometer).
Figure 5-3. Checking Pressure with Manometer
3. Open fuel supply valve and verify fuel pressure is
within specified values.
4. Record static fuel pressure:
NOTE: Fuel pressure can also be tested at the manome-
ter port on fuel shutoff valve shown in
NOTE: See Fuel Data Decal or spec sheet for correct
fuel pressure specifications. If fuel pressure is not within
specifications, contact local fuel supplier.
5. Close fuel valve when completed, but keep man-
ometer connected for future tests of generator
while starting, running, and under loads.
Performing Fuel System Leak Test
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.
All products are factory-tested before shipping to verify
the performance and integrity of the fuel system. How-
ever, 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 fuel solenoid valve.
See
Figure
5-4. 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.

Inspect 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.
