1. A multiple filter controller for monitoring two or more filters to detect when any of the said filters is malfunctioning, and is, hence, a malfunctioning filter, for allowing replacement and/or maintenance of the malfunctioning filter while the other of the said filters operates, and for polishing a fluid, wherein the multiple filter controller comprises: a first filter;a second filter;an inlet valve in operable communication with the first filter and the second filter, wherein the inlet valve provides the fluid to the first filter and to the second filter wherein the fluid originates from a supply station;an outlet valve in operable communication with the first filter and the second filter, wherein the outlet valve provides an outlet source for the fluid from the first filter and from the second filter;a first manifold;a first conduit connected to and extending from the first manifold;a second conduit connected to and extending from the first manifold, wherein the second conduit feeds the fluid from the multiple filter controller to a fuel pump;a bleed valve located downstream of the outlet valve and connected to the first conduit;a third conduit which connects the bleed valve to the supply station;a boost pump in a parallel configuration with a check valve, wherein the boost pump and the check valve are in operable communication with the outlet valve and with the bleed valve, and further wherein the boost pump and the check valve are downstream from the outlet valve and upstream from the bleed valve; anda vacuum gage in a parallel configuration with the boost pump and the check valve, wherein the vacuum gage is connected to a fourth conduit which is connected to a second manifold, wherein the second manifold connects a fifth conduit to the boost pump, a sixth conduit to the check valve, and a seventh conduit to the outlet valve; wherein the fluid is introduced into the multiple filter controller via the inlet valve, and passes into at least one of the first filter and the second filter, and further wherein the fluid is returned to the supply station by feeding the fluid into the third conduit via the bleed valve. 2. The fuel system of claim 1, wherein the multiple filter controller further comprises a vacuum switch which is disposed on the fourth conduit, wherein the vacuum switch detects a pressure level above a predetermined pressure level, wherein the pressure level is caused by a flow of the fluid through the malfunctioning filter, and wherein the vacuum switch responds to the pressure level, upon which response, the inlet valve is positioned to restrict the flow of the fluid to the malfunctioning filter and to permit the flow of the fluid to the other of the said filters, and further wherein, upon the response of the vacuum switch, the outlet valve is positioned to restrict the flow of the fluid from the malfunctioning filter and to permit the flow of the fluid from the other of the said filters. 3. The fuel system of claim 2, wherein the multiple filter controller further comprises a pressure gage positioned in parallel configuration to the boost pump and the vacuum gage and located downstream from the vacuum switch. 4. A fuel system, comprising: a fuel tank which holds a fuel source;a multiple filter controller, comprising: a first filter;a second filter;an inlet valve located upstream from the first filter and the second filter, wherein the inlet valve provides the fuel source from the fuel tank to the first filter and to the second filter;an outlet valve located downstream from the first filter and the second filter, wherein the outlet valve provides an outlet source for the fuel source from the first filter and from the second filter;a bleed valve located downstream of the outlet valve;a first conduit in line with the bleed valve;a second conduit in line with the bleed valve;a boost pump in a parallel configuration with a check valve, wherein the boost pump and the check valve are serially connected to and downstream from the outlet valve and upstream from the bleed valve; anda vacuum gage in a parallel configuration with the boost pump and the check valve, and further wherein the vacuum gage is connected to a third conduit which is in communication with the boost pump, the check valve, and the outlet valve;wherein the fuel source is introduced into the multiple filter controller via the inlet valve, and passes into at least one of the first filter and the second filter, and further wherein the fuel source is returned to the fuel tank by feeding the fuel source into the first conduit via the bleed valve;a fuel pump located downstream of the multiple filter controller, wherein the second conduit channels the fuel source to the fuel pump; andan injector pump located downstream of the fuel pump, wherein the fuel source flows from the fuel pump and into the injector pump. 5. The fuel system of claim 4, wherein the multiple filter controller further comprises a vacuum switch which is disposed on the third conduit, wherein the vacuum switch detects a pressure level above a predetermined pressure level, wherein the pressure level is caused by a flow of the fuel source through the first filter or the second filter which is now malfunctioning, and wherein the vacuum switch responds to the pressure level, upon which response, the inlet valve is positioned to restrict the flow of the fuel source to the malfunctioning filter and to permit the flow of the fuel source to the other of the filters, and further wherein, upon the response of the vacuum switch, the outlet valve is positioned to restrict the flow of the fuel source from the malfunctioning filter and to permit the flow of the fuel source from the other of the filters. 6. The fuel system of claim 5, wherein the multiple filter controller further comprises a pressure gage positioned in parallel configuration to the boost pump and the vacuum gage and located downstream from the vacuum switch.
