I've had my diesel injectors repaired or replaced here several times. Bought a turbo and the team was very helpful when I had a warranty claim with the turbo. Very friendly and helpful staff, always willing to help you out and answer questions even if you don't buy anything.

Yes, you can get rebuilt exchange components cheaper on the internet than from DFIPDX, but the quality, attention to detail, and tech support before and after the sale keep us coming back to DFIPDX as our ONLY fuel injection service provider.

Friendly staff ready to help you find exactly what you need, quick & easy.Tons of knowledge about application of specific parts and common upgrades.They ve hooked me up with CORRECT injectors for my truck, which was disassembled, two counties away (all via phone call).My grandparents had their Duramax s fuel pump go out abruptly; DFI had a replacement on their shelf ready to go.Super lucky to have them at our disposal here in the PNW!

Mark and his team are knowledgeable and courteous.Even though he spent time contacting his suppliers and vendors we ended up not finding a quality turbo assembly or rebuild kit that I needed. He didn't charge me for his time and I appreciate that.Businesses like this, and people like Mark are getting few and far between.

I bought new injectors for my 02 7.3L. The staff was very helpful and knowledgeable. And the injectors I needed were in stock. I definitely will use them again, and recommend to others.

I was told upfront they were two 2 weeks behind but to bring the pump and injectors in for estimate. I did, and they did. Mark was honest and extremely helpful. He told me when the work would be completed and it was. Excellent work and service. I don't know what they did but my old D19 Allis Chalmers starts easier and better than it has in all its 58 years.

My boyfriend brought his injectors and pump in to be rebuilt. They had all the parts in stock and their turn around time was impressive to rebuild it. Really happy with the results and their staff is extremely helpful! Thank you Diesel Fuel Injection Service!

This company was recommended by Pacific Truck and Trlr because we had a complicated and multiple problems with air getting into the filter on a '02 International DT 466. Kristy obtained the fuel filter base unit ( for $200 less than another place we called) and two other gentlemen there helped us diagnose other possible issues as well as cleaned off the plug / threads for the base we were going to install due to hairline cracks in the threads.. So friendly. SO KNOWLEDGEABLE and so willing to help! HIGHLY recommend these people. We put their sticker on our truck and made it to Libby Montana before a storm we needed to beat. GREAT transaction. Use DIESEL FUEL INJECTION SERVICE INC!!!Service: Auto engine diagnostic

Excellent customer service in every way. Fair prices, very knowledgeable, friendly, and respectful. Threw in a few things at no charge and took as much time as we needed n order to answer our questions and proactively gave us information that helped us a lot. I haven t seen this quality of customer service since I was young. If you need diesel injector work, you will not go wrong choosing this shop! I give this shop and 10 out of 5!!

Ok here is the scoop. Mark is a great guy. I dealt with him off a hunch on something totally unrelated (but engine related) to his specific services and he went above and beyond when he didn't have to. I am very thankful. If his craftsmanship is anything like his follow through then it's awesome.

I don't know why this place has such a good reviews. I ask them to fully rebuild my cummins n14 fuel injectors (6 of them) so for you to understand the quality of their work , 1 mount later I had to replace 4 of them already again. Later I gave them 1 (100% ) bad injector, guess what? They checked and said it's a good working injector. Think twice before you do business with this place.

Total rip off. Took 8 diesel fuel injectors in for testing and cleaning. Told ALL 8 injector coils failed resistance, no good. Need all new ones. Went to pick up and didn't even give me back the correct ones. Total rip off!!!! Truck was running fine. Blew a head, so figured it wouldn't hurt to have injectors cleaned. Well it hurt.

Was looking to have a 35 year old injection pump rebuilt for a Toyota truck we're restoring. Received a word-of-mouth reference for Diesel Fuel Injection Services in Portland, and they didn't disappoint. Well worth the five-and-a-half hour drive from Spokane, WA. Mark and his staff are very knowledgeable and had the pump looking factory fresh. Would definitely recommend, and will seek out for any future diesel needs!

These folks did a bang up job on my fi pump and were more than patient with my dumb questions. Nice people, fair prices, quality work. Overall a very pleasant experience.
