13-2
OVERVIEW
The fuel system consists of a fuel neck and cap, 20-gallon fuel tank, tank sending
unit, mechanical fuel gauge and electric fuel pump aft of the center section. The ES
40105 Electric fuel pump is a 12V DC solid-state pump. This serves as an auxiliary fuel
pump. The VA-261 Fuel Strainer at the outlet of the fuel tank prevents any large foreign
objects from proceeding into the rest of the fuel system. Forward of the center section,
in order; there is the fuel valve, fuel flow transducer, gascolator, Engine driven fuel
pump, and the fuel manifold. The fuel valve provides the ability to permit or prevent fuel
flow to the fuel system downstream of the fuel valve. The manifold feeds the fuel
pressure sender, fuel return line and the left and right carburetors. The gascolator
serves as the primary fuel filter and water trap. Sample the gascolator sump frequently
to monitor the amount of water introduced into the fuel system. The gascolator and fine
fuel screen requires inspection and cleaning at regular intervals (at least annually).
