Uhm...yeah...it will...I ran an adrenaline pump with the newer oil rails on my truck for over two years.I was under the impression that the 03 and early 04's and weaker pumps which is what the loss of pressure is caused by not necessarily the oil rails. Is that not correct because I feel pretty confident in that. the adrenaline pump won't work with the newer oil systems.
You can't. You need the rocker boxes, valve covers, glow plug harness, etc...that's a pretty solid hpo setup I didn't know I could just ditch the log style and update to the new style
