Test Fuel System for Leaks(LP and Dual
Fuel Engines Only)
1. Obtain a leak check squirt bottle or pump spray
bottle.
2. Fill the bottle with an approved leak check
solution.
3. Spray a generous amount of the solution on the
fuel system fuel lines and connections, starting
at the storage container.
4. Wait approximately 15-60 seconds then
perform a visual inspection of the fuel system.
Leaks will cause the solution to bubble.
5. Repair any leaks before continuing.
6. Crank the engine through several revolutions.
This will energize the fuel lock-off and allow fuel
to flow to the pressure regulator/converter.
Apply additional leak check solution to the
regulator/converter fuel connections and
housing. Repeat leak inspection as listed
above.
7. Repair any fuel leaks before continuing.
