Re: Fuel pump? Are your talking about the fuel supply pump or diesel injector pump. It is possible to install an electric fuel pump to replace a mechanical pump on some diesel engines. Make sure the new electrical Pump has the correct Flow/Pressure specifications/requirements needed for this engine. Make a Steel plate with gasket to fit and bolt over the old removed fuel hole pump to seal this area on the motor. If this failure is for your Injection pump, this failure always requires the installation of a new or rebuilt pump available from a reputable Diesel Rebuild service company, and don't forget to replace the fuel filter to insure no foreign particles get into injectors.
