Bosch Fuel Injection Pumps
SKIP ThE HASSLE. COME TO THE EXPERTS.
​
An oft-overlooked aspect of classic Mercedes-Benz restoration and repair, Bosch fuel injection pumps bring an entirely unique set of challenges and require not only intricate expertise, but also unique, expensive and hard to find equipment to even perform the service.
​
Bosch fuel injection pumps don't just need a deep clean, they need service at the level of the rest of your vehicle, and Black Forest is one of the only shops in the country specializing in the restoration of Bosch fuel injection pumps.
