About Us

Associated Diesel was founded in 1968. Since that time we have rebuilt thousands of diesel injection pumps and injectors for automotive, truck, marine, construction and industrial engines. We service AMBAC(American Bosch), Robert Bosch, Delphi Lucas Varity(CAV), Stanadyne (RoosaMaster), Caterpillar, Detroit Diesel, and Cummins Diesel Fuel Injection systems. In addition to fuel injection repair, we are also a Baldwin Filter Distributor and can supply lube oil, fuel, air, coolant and hydraulic filters for your heavy duty equipment. We are located in the Dorchester section of Boston at the corner of Freeport Street and Freeport Way.
