Abstract
A hose connection (51) includes mounting structure (32) and suction structure (46) having an axis (B). The suction structure is mounted to the mounting structure such that the suction structure can rotate with respect to the mounting structure about the axis. The hose connection includes a hose (26′) coupled to the suction structure.
Claims18
A hose connection comprising:
- mounting structure,
- suction structure having an axis the suction structure being mounted to the mounting, and
- a hose coupled to the suction structure,
- wherein the mounting structure has a resilient locking structure and the suction structure includes surfaces defining at least one recess, the locking structure being engaged with the recess to limit axial movement of the suction structure while permitting the suction structure to rotate freely with respect to the mounting structure about the axis without substantial interference there-between so as to avoid twisting forces that may be exerted on the hose,
- wherein the suction structure includes a tube member having first and second open ends, the first open end of the tube member being coupled with the hose, the second open end being constructed and arranged to rest on a bottom surface of a fuel tank.

A fuel supply system comprising:
- a fuel tank having a primary portion and an auxiliary portion,
- a fuel pump assembly in the primary portion, the fuel pump assembly including a jet pump,
- mounting structure in the auxiliary portion,
- suction structure having an axis and first and second ends, the suction structure being mounted to a bottom portion of the mounting structure, and
- a hose coupled at one end thereof to the first end of the suction structure and coupled at another end to the jet pump such that fuel in the auxiliary portion of the fuel tank can be drawn by the jet pump through the suction structure and hose to the primary portion of the fuel tank,
- wherein the mounting structure has a resilient locking structure and the suction structure includes surfaces defining at least one recess, the locking structure being engaged with the recess to prevent axial movement of the suction structure, and
- wherein the suction structure is mounted to the mounting structure such that the suction structure can rotate freely, with respect to the mounting structure, about the axis without substantial interference there-between so as to avoid twisting forces that may be exerted on the hose and wherein the second end of the suction structure engages a bottom of the auxiliary portion of the fuel tank.
