the disel fuel lift pump. (can be hand pumped also) is that the main fuel pump? as the pipe from fuel tank goes to the fuel hand prime lift pump, then to the filter housing, then two pipes out to the fuel injection pump, a hose to either end, (obvisouly to feed two injectrs each) two hoses with banjo unions . One hose feeds two injectors, on the fuel injection pump, Is there a internal fuel pump which also draws fuel in?
