Little story here just in case anyone is wondering if they should buy anything from DAP. I bought a set of injectors last spring because my copper washers were leaking compression back into the fuel tank and I figured at 180k with the injectors out I might as well throw in a new set. For 400 bucks I didn't have much to loose. Immediately I could tell the motor was much quieter and it had a ton more power. (Oh still getting 21+ mpg too) Within the last month or two I have developed a slight miss in the #3 injector which is progressively getting worse. I pulled it apart and found the pintle wasn't moving up and down easily even after cleaning thoroughly. I called Jacob and told him about the problem. They offered to test all 6 for free and fix / replace any that were not working properly for free. Well I decide I wanted to go bigger and try a set of SAC nozzles. Once I send in my old ones he is sending a set of SAC 125s for a very low cost! (Surprised me how low) I have never worked with a company willing to help a customer out like they do. If you need a place for parts support them! They will work to satisfy you, and they support this forum and CF. 

I ordered parts from DAP and they treated me well also. I will be talking to them soon.

good place

Quallity parts at a good price. Got my RV275's and ARP studs there

I agree,I got a fass and a Industrial injection VP44 and they were great to deal with.

Funny thing I had a miss for a long time, could never figure it out, no codes and runs fine when not loaded but with a trailer behind I get a steady miss at about 60mph. So after talking with a hole lot of people, most suggested injectors, so I got a set of 60hp from dap and behold the miss is gone. Now today I pull a trailer again with 6k truck on it and the miss came back, might have to call dap and see what they say.
