Pump System and Method of Use

Abstract

A multi-pump assembly and method of use including a housing and at least two pumps contained within the housing is described, wherein each pump has a performance level. In an embodiment, the performance level of each pump is the same. In another embodiment, the performance level of each pump is different. The assembly may also include a common electrical inlet, a common fuel inlet connection, a common fuel outlet connection, a pressure regulator, a final filter, an outlet check valve connected to each pump, a plurality of over pressure relief valves connected to each pump and an over pressure relief passage formed around the pumps in the housing, an electronic controller capable of operating each pump independently, a fuel filter and a pressure regulator in the housing to form a returnless fuel supply, and/or a final filter. The assembly may be used in a multiple carburetor or fuel injection applications.

1 . A multi-pump assembly comprising:
 a housing;   at least two pumps contained in the housing;   an outlet check valve inside each pump; and   an over pressure relief passage formed around the pumps in the housing;   wherein each pump has a performance level.   
     
     
         2 . The multi-pump assembly of  claim 1  wherein the performance level of each pump is the same. 
     
     
         3 . The multi-pump assembly of  claim 1  wherein the performance level of each pump is different. 
     
     
         4 . The multi-pump assembly of  claim 1  further comprising a common electrical inlet. 
     
     
         5 . The multi-pump assembly of  claim 1  further comprising a common fuel inlet connection. 
     
     
         6 . The multi-pump assembly of  claim 1  further comprising a common fuel outlet connection. 
     
     
         7 . The multi-pump assembly of  claim 1  further comprising a pressure regulator. 
     
     
         8 . The multi-pump assembly of  claim 1  further comprising a final filter. 
     
     
         9 . The multi-pump assembly of  claim 1  further comprising an electronic controller capable of operating each pump independently. 
     
     
         10 . The multi-pump assembly of  claim 1  wherein the multi-pump assembly is capable of being used in a multiple carburetor or fuel injection applications. 
     
     
         11 . The multi-pump assembly of  claim 1  further comprising a fuel filter and a pressure regulator in the housing to form a returnless fuel supply. 
     
     
         12 . The multi-pump assembly of  claim 1  further comprising a final filter. 
     
     
         13 . A method of using a multi-pump assembly, wherein the pump assembly comprises:
 a housing;   at least two pumps contained in the housing;   an outlet check valve inside each pump; and   an over pressure relief passage formed around the pumps in the housing;   wherein each pump has a performance level;   
       which method comprises the step of:
 controlling each pump individually. 
 
     
     
         14 . The method of  claim 13  further comprising integrating a pressure regulator. 
     
     
         15 . The method of  claim 13  further comprising integrating a final filter. 
     
     
         16 . The method of  claim 13  further comprising a fuel filter and a pressure regulator into the housing to form a returnless fuel supply.
