Abstract
A marine fuel supply system for a fuel injected engine (10) deadheads a high pressure fuel line (27) with a closed-end connection to the fuel injectors (24) without a recirculating return fuel line to the fuel injection pump (25) and without a return fuel line to the remote fuel tank (29). A differential pressure transducer (33) senses differential pressure across the fuel injector (24) between the high pressure fuel line (27) and the low pressure induction manifold (17) and turns off the fuel pump (25) above a first value of relative differential pressure and turns on fuel pump (25) at a second value below the first value, to maintain the fuel pressure in the high pressure line (27) within a given range relative to induction manifold pressure.
