Restoring a Bosch Fuel Injection Pump:
The Walk-Through

Take a rarely seen inside look at restoring a Bosch fuel injection pump

As time passes technology progresses and once state-of-the-art systems are passed up and fall by the wayside. When it comes to regular appliances like a washing machine, we hardly take notice. But when it comes to collectibles, such as classic cars, these technologies may have been surpassed, but we can't afford to forget them. 

Carburetors gave way to mechanical fuel injection, which itself was surpassed by electronic fuel injection within decades. While fuel injection pumps remain an important part of industries such as shipping and agriculture, gasoline fuel injection pumps were left behind by the dawn of the 80's leaving experts few and far between when it comes to their design, operation and restoration. 


Despite prices skyrocketing within the classic car market, fuel injection pumps have fallen off the radar of most shops, but not at Black Forest LLC. Our fuel injection pump shop is one of the premier pump shops in the country and our specialists love nothing more than diving into a new pump. From simply testing and cleaning, to replating and refinishing, to re-engineering parts and developing new methods, our restorations go further than your typical deep clean.
