Derek's Diesel Service Inc

I had my fuel injectors serviced here a couple years ago in hopes of a good cleaning fix the two leaky ones I had. Even though it wasn't successful I can't complain because that's not their fault and they went above and beyond to find replacement pintle caps for the one that was melted and the other that was missing.

The staff at Derek’s diesel are amazing at what they do. I had an issue with a Cummins 8.3 in a ford l8000 that no one could figure out, I had spent money on fuel lift pumps injectors and other parts such as throttle linkages fuel lines etc, Joe simply asked what the problem was I told him it was very sluggish and slow going up any sort of incline and he put a ball valve on the counter and said you need this. It was the return ball valve on the back of the injector pump.

I replaced this part and seals and took it for a test drive, it worked perfectly. After 1 week of not being in service and 3-4 opinions Derek’s diesel solved my mystery and put me back to work. Thanks Joe for your help
