A gravity-fed, float-controlled fuel system (Figure 4) is used to supply fuel to the pulse jet engine.
The fuel system consists of the fuel tank assembly and the float bowl assembly. The fuel tank assembly
consists of a fuel tank, a cap, a fuel drain cock, a shutoff valve, a fuel sediment strainer, a fuel filter, and
a fuel hose assembly. The float bowl assembly consists of the float bowl, float assembly support rod,
adjustment knob, float adjuster support bracket, float bowl toggle valve, fuel tube, and hose clamps.
Fuel flows by gravity from the fuel tank through the fuel line valve, strainer, fuel filter, and fuel line to
the float bowl. The float in the bowl maintains the fuel at the proper level with respect to the fuel-
metering jet in the engine head.
