4. Never bend the flexible fuel line to avoid using an elbow. Bending the flexible line decreases its ability to absorb vibrations and defeats its
purpose, as well as constricts the actual fuel flow. See Figure 5.5.
5. Check for leaks by spraying all connection points with a soap solution made of dishwashing soap and water. You should not see the solution be
“blown away” or form “bubbles”. Next, check the gas pressure at the regulator in the generator by following these steps.
– Close gas supply valve.
– Remove the top gas pressure test port from the regulator (see Figure 5.6) and install the gas pressure tester (manometer).
– Open the gas supply valve and ensure that the pressure is within the specified values.
NOTE: See owner’s manual or spec sheet for proper fuel pressure specifications. If the gas pressure is not within specifications, contact
the local gas supplier.
4) Close gas valve when completed.
