Abstract
A two-stage marine fuel pump (10). A first pump stage (S1) has a fuel inlet (24) and a fuel outlet (26). A second pump stage (S2) has a separate fuel inlet (28) and fuel outlet (30). Each pump stage is stand alone such that while the outlet of the first pump stage can be routed to the inlet of the second pump stage, the pump can be otherwise configured. In these other configurations, there is one path for routing fuel to the fuel inlet of the first pump stage and from the outlet thereof, and a separate path for routing fuel to the inlet of the second pump stage and from the outlet thereof. In these alternate configurations fuel pumped from the first stage of the pump is delivered other than to the fuel inlet of the second pump stage, and fuel supplied to the inlet of the second pump stage is delivered other than from the fuel outlet of the first pump stage.
