Fuel Injection

Pumps – Rebuilt & Repaired

We rebuild and repair all makes and models of the traditional mechanical controlled pumps including Bosch, Stanadyne, Rosamaster, CAV, Delphi, Simms, CAT, and Cummins. We also service most makes and models of electronic controlled pumps. Bosch, Delphi, Denso, and Zexel pumps are just some of the more popular brand names we service. Whether you need partial repairs or complete rebuilds, we will be happy to provide top quality workmanship at a competitive price.


Fuel Injection – Mechanical

Since 1958, DSGB Inc. has been a leader in rebuilding diesel fuel injectors. We are authorized by the leading manufacturers to disassemble and inspect for worn or faulty parts. The injectors are back to brand new after we’re done with them!

We learned very early that the nozzle is where 99% of the failure happens. When we rebuild the injector with an OEM nozzle, it lengthens the life of that injector.


Leader in common rail technology

DSGB Inc. is the ONLY Bosch authorized common-rail injection dealer in WI. With our Bosch 815 Test stand and the newly innovative Bosch DCI 700 test stand, we are able to rebuild Bosch pumps and injectors that qualify for the genuine Bosch rebuild label. We stock a full line of rebuilt Bosch common rail injectors and pumps. See what we have available for sale now!


State-of-the-Art Clean Room

We assemble the common rail injectors and common rail pumps in the dust-free and dirt-free clean room because dust and dirt particles can interfere with the rebuilding process.
