I bought two of these units from a different supplier this Dorman product works as advertised but it will fail in the future just like the OEM did. They make better units out there for these trucks now and they are made in the USA much better design. Diesel parts Canada would do themselves a favor by getting these newer type to sell at their store instead of these Dorman ficm's. I also have used the Aliant ficm and it worked flawlessly for about a year now.
I was very happy to find a local site, not only in Canada but in my home city. Very pleased with the parts, price, and availability.
I'll be a repeat customer for sure.
