Abstract
The fuel pumping system for delivering fuel to an engine includes a fuel transfer circuit for directing fuel from a fuel supply tank to the engine, a fuel boost pump, a main fuel pump and an accumulator device positioned along the transfer circuit between the boost pump and the engine for accumulating fuel and vapor so as to provide a reserve supply of fuel to the engine while minimizing the amount of undissolved vapor delivered to the engine. The system includes a return passage communicating, at one end, with the accumulator and at an opposite end with the fuel transfer circuit upstream of the boost pump for directing fuel and vapor from the accumulator into the transfer circuit.
