Background of the Invention
Generally the fuel system of vehicles having fuel tank, fuel lines, fuel sedimentor, fuel filter,
high pressure pump, high pressure pipe, common fuel rail and electronically controlled fuel
injectors.
The primary function of the fuel system in automobiles is to carry fuel from fuel tank to the
fuel injectors. In addition to the fuel supply to the injectors, the said fuel system also carry the
excess fuel available at common rail, back to the fuel tank mounted on the chassis frame.
Generally sedimentor and fuel filter are mounted in engine compartment with the help of
mounting brackets, so that the said fuel sedimentor and filter remains fixed at one location
when the vehicle is moving. The function of fuel sedimentor is to separate the water available
in fuel and that of the fuel filter is to trap the impurities available in fuel from reaching the fuel
injector.
The mounting bracket for fuel sedimentor and fuel filter is bolted to wheel arch of vehicle in
the engine compartment. For maintainance, the sedimentor drain plug is not easly accessible

Now refering to figure-01 which shows the front view of the fuel filter mounting means 4 and sedimentor mounting means 3 on which the fuel filter 9 and sedimentor 10 are mounted respectively. Said fuel filter mounting means 9 and sedimentor mounting means 10 are mounted on base plate assembly 28. The said base plate assembly 28 is mounted/attached or fastened to the inner wheel arch 12 of of vehicle by using screws 11. The function of fuel sedimentor 9 is to separate the water available in fuel and that of the fuel filter 10 is to trap the impurities available in fuel from reaching the fuel injector.
Now refering to figure-02 which shows the isometric view of the said base plate assembly. The said base plate assembly 28 comprises base plate 2 and the support plate 1 which is elbow shaped. The said base plate 2 is made of sheet metal having appropriate thickness. The cross section of said base plate 2 is derived such that it withstands the durability requirements for the whole life cycle of the vehicle. Said base plate 2 is having at least three embossing 29 for increasing the strength of the said base plate 2. The said embossings 29 avoids the said base plate from deforming due to torque applied on it while fastening to the wheel arch 12. The said base plate 2 having at least three holes 15 pierced to it. The said
