IN-TANK FUEL RESERVOIR WITH FUEL LEVEL SENSOR

摘要

A fuel delivery system for automotive engine and like applications comprises a canister (12) for positioning within a fuel tank (16) so as to be surrounded by fuel in the tank. An electric-motor fuel pump (26) has an inlet (28) and an outlet (30) for feeding fuel under pressure from the tank to the engine. Excess fuel is returned from the engine to the canister. A fuel level sensor includes a pressure sensor (64) positioned at a lower portion of the canister and responsive to head pressure within the canister and within the surrounding tank for providing an electrical signal as a function of a difference between such pressures. An indicator (63) is responsive to such electrical signal for displaying tank fuel level to an operator.
