MAINTENANCE

G424 engine requires
maintenance. Suggested maintenance requirements
are contained in this section. The owner should,
however, develop his own maintenance schedule
using the requirements listed in this section and any
other necessary requirements resulting from optional
additions to the engine system.

Test Fuel System for Leaks

• Obtain a pump spray bottle.
• Fill with an approved leak test solution or a mixture
of water and dish soap.
• Spray a generous amount of the solution on the
entire fuel system including the fuel storage
container and fuel lines.
• Wait approximately 15-60 seconds then perform a
visual inspection of entire fuel system.
• Leaks will cause the soapy solution to bubble.
• Repair any leaks before continuing.
• Crank the engine through several revolutions. This
will energize the fuel lock and allow fuel to flow to the
pressure regulator/vaporizer. Apply additional leak
test solution to this portion of the fuel system and
inspect as above.
• Repair any fuel leaks before continuing.
