Abstract

A fuel system (100) includes an air residence chamber (101) operative to receive fuel from a fuel tank and allow degassed air to separate from fuel to an upper portion (101a), and a boost pump (103) including a boost pump inlet (103a) and a boost pump outlet (103b). The boost pump inlet (103a) is in fluid communication with a lower portion of the air residence chamber (101) to pump fluid from the air residence chamber (101). The system also includes an accumulator (107) in fluid communication with the boost pump outlet (103b). The accumulator (105) includes a reservoir (107) having a reservoir inlet (107a) in fluid communication with the boost pump outlet (103b) and a reservoir outlet (107b). The accumulator (105) also includes a piston (109) slidably disposed in the reservoir (107). The piston (109) is operative to push fluid through the reservoir outlet (107b) when a pump pressure of the boost pump (103) drops below a predetermined pressure value.
