FUEL SYSTEM

GENERAL
The welded aluminum tank is located directly behind the firewall (capacity 13 gallons). Fuel is gravity fed
from tank to gascolator filter assembly and from gascolator to carburetor. A positive and accurate method
for checking fuel supply is provided with a float type fuel gauge located directly on top of the fuel tank deck.
The fuel shutoff valve is readily accessible from front or rear seat, being located on the engine control panel.
A primer is furnished to aid in cold weather starting.

GASCOLATOR FILTER ASSEMBLY
Located on the engine side of the firewall, the gascolator assembly affords a means of straining sediment
and foreign matter from the fuel flow. The gascolator is located at the lowest point in the system, therefore,
water is collected in the sediment bulb and care should be taken to check for its presence.

CAUTION: This check can be accomplished visually and should be a daily check. Operating
in cold weather and storing in warm hanger with an unfilled tank, also operating in a climate
where high humidity ratio is prevalent, are most probable causes for condensation and the
presence of water in the fuel system.

Care should be taken to replace the bowl securely and re-safety. Gascolator gasket should not be used
more than once before being replaced. When draining gascolator bowl, filter screen should be cleaned and
checked for enlarged mesh or damage.

PRIMER
For cold weather starting, three slow movements of the primer pump as the propeller is being pulled
through will force fuel directly into the induction system assuring quick, positive starting.
