Checking Fuel Pressure

Proceed as follows to check fuel pressure at
fuel regulator in the generator.
1.
Close fuel supply valve.
2.
See Figure 5-4. Remove top fuel pressure
test port from fuel regulator and install fuel
pressure tester (manometer).
Figure 5-4. 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
manometer port on fuel shutoff valve shown in
Figure 5-2.
NOTE: See fuel data decal or spec sheet for
correct fuel pressure specifications. Contact
local fuel supplier if fuel pressure is not within
specifications.
5.
Close fuel supply valve when completed.
Keep manometer 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 ship-
ping to verify 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 mainte-
nance.

Figure 5-5. Connection Points to Leak
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.
