getting ready to install a regulated return for a buddy. Ive did studs, egr deletes, etc on 6.0 so pretty familiar with them. Im doing this cab on, just curious iuf anyone has installed one, how long it took them, and if yal may have any tips to make it easier on me. thanks

 

Depends on what kit you're using I guess. I'm sure it could be done cab on, but probably a PITA. I've removed the plugs in the back of the heads for the fuel rails and hooked up my fuel lines for my vegistroke there cab on, done it on a couple of them now, PITA. You'll have to make special tools to get them out cab on though. A regular allen wont fit in. I took an allen wrench, and cut the short end even shorter, like 1/2 as short. Slide it in, and from under the truck use a 1/4" drive 6mm socket on the end of the allen, then put a 1/4" drive extension on and use it like a breaker bar. They'll snap hard to break loose, but once you do that they come out by hand real easy.
