This FPM architecture is a single pump design for use in systems with more than one fuel chamber where an active fuel transfer feature, an auxiliary (secondary or transfer) module, and fuel transfer line are a
15、dded to move fuel from one chamber to another chamber. The primary module typically houses the active fuel transfer feature to draw fuel from the secondary module into the primary reservoir. Fuel transfer line may be permanently fixed to the primary module or connected using quick connect device. 1.
16、3.10.1 Transfer Module. A secondary or transfer module designed to complement a primary fuel module in a dual FPM system. This component typically features a fuel transfer inlet, fuel level sensor, and flange which may incorporate tank venting features. 1.3.11 Auxiliary Fuel Tank Systems. The FPM is
17、 designed for an intermittent use gasoline or diesel system where the primary energy source is electricity or a gaseous fuel such as Liquefied Petroleum (LPG) or Compressed Natural Gas (CNG). This system may remain unpowered for extended periods of time or powered only at initial starts or high powe
