Abstract: In accordance with at least one aspect of this disclosure, a system includes an in-tank fuel pump configured to be disposed in a fuel tank to supply fuel from the fuel tank to a fuel line at a first pressure. A boost pump is configured to be disposed in the fuel line to receive fuel from the in-tank fuel pump and supply the fuel to one or more downstream components at a boost pressure. An augmentation pump system is configured to be disposed in the fuel line to receive fuel from the boost pump and to supply fuel at a second pressure to one of, at least one fuel consuming component downstream of the augmentation pump system, or an in-tank ejector pump, based on an operational state of the in-tank fuel pump.

Abstract: An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
