LLY: What will I need

[04llygmc]

Getting ready to put some bigger injectors in my truck. What all will I need to replace while in there, seals, ect. Also what are your opinions on swapping a lbz pump vs. a modded regulator from wicked diesel or another vendor? My stock cp3 is in good shape and holds good rail psi. Planning on going 45% on injectors. Thanks for any advice.

As a good measure, id replace all the o-rings, crush seals. One of the guys here can prolly get you part numbers, price, etc. Im only familur with the LB7 I, like a dumbass the 1st time bought all mine from my local stealership and paied about $200 I have since sourced it all localy exept the copper combustion chamber seal but there avalible from other sources than GM directly
