Abstract
The present invention provides a fuel delivery system for a saddle fuel tank wherein a fuel pump and a jet pump are positioned within an active side of the tank. The jet pump is directly driven by the fuel pump to draw the fuel from a passive side of the tank to the active side of the tank.
Claims12
A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
- a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an Inlet and an outlet;
- a diverter having an inlet in fluid communication with said fuel pump cutlet, a first outlet being in fluid communication with the engine, and a second outlet;
- a jet pump adapted to be positioned in the first side of said saddle a tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank;
- and
- a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
- wherein said diverter is a T-shaped valve;
- and
- wherein said jet pump is T-shaped and includes an internally positioned nozzle.
A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
- a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an inlet and an outlet;
- a diverter having an inlet in fluid communication with said fuel pump outlet, a first outlet being in fluid communication with the engine, and a second outlet;
- a jet pump adapted to be positioned in the first side of said saddle tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank;
- and
- a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
- wherein said diverter is a parallel pressure relief valve.
A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
- a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an inlet and an outlet;
- a diverter having an inlet in fluid communication with said fuel pump outlet, a first outlet being in fluid communication with the engine, and a second outlet;
- a jet pump adapted to be positioned in the first side of said saddle tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank;
- and
- a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
- wherein said diverter and said jet pump are an integrated component.
