Derek's Diesel Service Inc

Awesome super nice, got parts for my diesel pusher, Cummins engine, fair prices! I'll definitely deal with them again!

Best diesel parts service around. No need to look anywhere else

I had 3 injectors and injector pump done by them this summer for my old loader. I will say a big thanks. Due to my faults, I had to go to them about 5 or 6 times. Never a complaint on being a pain. I was highly recommended by a really good mechanic in Parry Sound to use them. They stock a lot of parts as well from what you can see at front desk.

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

Had a set of injectors cleaned and tested at this facility. From my inquiring phone call to picking up the injectors,the service was exceptional. Professional staff, efficient and knowledgeable. Will likely be a life time customer.HIGHLY recommend!Cheers!

Found out that these fuel specialists worked on old injector pumps too late and i could have same many waisted hours trying repairs myself. Amazing repairs on my 50 year old CAV pump for my tractor. Installed the pump and it has never run better. Highly recommend.

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.

Super fast service on a 30 year old Bosch injector pump from my 93 Beneteau sailboat. Friendly and very courteous. 5 stars.

Amazing people great staff great service and they know everything about diesel see you again guys
