Some delete it some keep it. As long as it's keeping its seal I don't think it hurts to have a last stop filter incase something got by your lift pump filters. Just my opinion
absolutely not....
where do guys come up with these "extend your injector life with....." ideas
Cylinders 4 and 6 cannot disperse heat as quick as the rest of the truck with the stock manifolds. You telling me that has no effect on the way those injectors perform? I thought that poor design was part of the reason why the LB7 was killing injectors so easily? I could be full of it but makes sense to me, heat is a killer less heat things live longer function better IMO.
Same exact manifolds were used until 2010, GM didn't change until 2011 for the lml. LB7 injectors had/have several issues, but an exhaust manifold is NOT one of them.
Swapping the drivers side manifold for a mostly stock truck might drop egts what 75 degrees at best. How is that gonna change anything? Most injector failures are either dribbling nozzles because some soot or debris hangs the needle in the vco nozzle open, or the ball seat erodes over time causing high return rates allowing the injector to open on it's own. How is either of those failures heat related. I've seen more failures at the back of the rail on 7 & 8(where any contaminants woyld settle out and get into an injector 1st), so there goes your 4 & 6 theory.
I would recommend sticking with a CAT fuel filter setup in the factory location. Can't have to much filtration on the LB7.
