Thinking about putting lly rails on my truck so i can get a dual cp3 kit sooner. Will I need new injector lines since the pressure sensor will move to the middle of the rail instead of the back? The lly rails are bridged somewhere to keep the pressure equalized still??

Bump. Anyone have an opinion? Should I order the lbz kit and get my hp lines from someone else? Or buy a full lly kit and change the fuel rails?

You will have to change injector lines because the fittings on the rail are different on the LLY rail.
