Fuel Pump Assemblies . Bosch supplied the industry’s first fuel injection system with a high pressure electric fuel pump in 1967. Since then, Bosch has stood at the forefront of fuel system technology, providing fuel pumps to virtually all vehicle manufacturers. UNIVERSAL FUEL PUMPS. Carter’s first-generation mechanical fuel pumps are available for most domestic and imported passenger cars, trucks, marine, and industrial engines. These pumps are offered in die-cast and billet aluminum as well as stamped steel to accommodate various needs on the road. Try not to use channel lock pliers, they will break the plastic clamps. Squeeze and wiggle the hose until it slides off the fuel tank. Remove the safety clips on the two fuel lines at the pump.

I guess I am back to the auto parts store to get the oil sending unit that supposedly the power supply for the fuel pump goes through.
