From where does fuel get directed to the engine driven low pressure fuel pump?

The flow of fuel to the engine driven low pressure fuel pump in the T-6B begins at the primary jet pump. This component plays a crucial role in the fuel system by ensuring a consistent and adequate supply of fuel from the fuel tanks to the low pressure fuel pump. The primary jet pump utilizes the venturi effect and relies on fuel flow from the system to create suction, drawing fuel from the collector tank to the low pressure pump, which then sends it to the engine.

The other components, while integral to the overall fuel management system, serve different purposes. For instance, the collector tank pressure pump is primarily involved in maintaining pressure within the collector tank, while the transfer jet pump typically assists in transferring fuel between tanks or from a tank to the collector. The fuel management unit coordinates various fuel system operations, managing flow and pressure but does not serve as the direct source of fuel flow to the low pressure fuel pump. Hence, understanding the specific function of the primary jet pump clarifies its role in directing fuel to the engine-driven low pressure fuel pump.
