Test Fuel System for Leaks (LP

bottle.

solution.
z Spray a generous amount of the solution on the
fuel system fuel lines and connections, starting
at the storage container.
z Wait approximately 15-60 seconds then perform
a visual inspection of the fuel system. Leaks will
cause the solution to bubble.

z Crank the engine through several revolutions.
This will energize the fuel lock-off and allow fuel
to flow to the pressure regulator/converter.

regulator/converter fuel connections and
housing. Repeat leak inspection as listed above.
