Simple: To increase integration and reduce costs. The auto mfgrs.
prefer to buy fewer total assemblies from suppliers to cut down on costs
such as separate handling, installation, shipping, purchase contracts,
parallel paper trails, tracking systems, project managers, installation
effort, etc. By putting the fuel pump with the "sending" unit, the fuel
pump and gage sender (and, in the case of the LH cars, the fuel filter)
get incorporated into one purchased "part".
