OK, sorry I started this and have not replied... had a family emergency over the weekend. I am still reading through some of these, but my truck is an '03, the application guide clearly stated that the '03 and older trucks could use this system. To answer one of the earlier posts, no, there was nothing wrong with installation of the system. The hoses were routed correctly and it is impossible to switch the filter canisters as the pipe nipple sizes are different in the filter head. I drove 1500 miles this weekend and had no problems, good power, oil pressure, etc. I guess i was lucky... I hope.
have to go to work, will post later
