I purchased a lift pump from hoeslidiesel.com. The pump was shown as a Cummins p/n 3990105. The pump received has Carter stamped on the bottom of the motor housing and 01055CO2A on the pump. No labels anywhere on the pump. It looks new, no marks on the input or output ports that would indicate it has ever been used. It also has residue of diesel fuel seeping out of the pump. Anyone else who has purchased from Hoesli diesel have similiar experience. Anyone with ideas?
