Abstract
A fuel system includes a fuel pump and a jet pump assembly. The jet pump assembly includes a first fuel passage defined by a first tube. The jet pump assembly also includes a second fuel passage which receives pressurized fuel from the fuel pump, the second fuel passage having a primary orifice centered about and extending along a primary orifice axis such that the primary orifice axis is directed into the first fuel passage and such that the primary orifice introduces a first flow of fuel into the first fuel passage. The second fuel passage also has a secondary orifice centered about and extending along a secondary orifice axis which is not coincident with the primary orifice axis and which is directed at an inner surface of the first tube and the secondary orifice introduces a second flow of fuel into the first fuel passage which impinges the inner surface.
