MMcCowan,
I sent mine in for a rebuild, they supposedly were shipping it back to me and I never got it. My rep called me to let me know they had thrown away my address. I finally received a box and all I got was the new motor and T-block. I contacted the rep I went thru and he notified them of the mistake. They said that they had lost my original pump and thet they felt they should not have to replace my old pump since all I paid for was the upgrade. So... after all that they sent me someone elses main body with 2 new filters and a pump bracket. Everything was packaged terribly and the filters were beat to he--. The little check ball was wrapped up inside one of the pieces of newspaper they casually threw inside as "packaging". I now have a pump assembly with 2 different serial numbers (neither of which am I directly tied to)that I have to assemble (not real difficult) and no paperwork to submit for the supposed lifetime warranty. In the mean time I am nursing a holle blue along trying to keep the truck going. Not all so bad if I was in one location all the time, but I am a field tech and travel all over the country. I don't have the luxury of having extended down time flexability. This was a major pain in the a--. It would have been better if I had bought a new one from someone that keeps parts in stock.
