cpi fuel lines

has any body ever changed the fuel lines on the CPI unit? i was able to get some new lines but not the entire unit. i think mine are going bad and need to be changed. i can move them back and forth on the injectors and the injectors don't move. any body have a step by step process to follow? the cpi isn't leaking just the fuel lines. i'll change the cpi when it needs it.any idea on process?

So are you talking about the 6 little lines going in to the bottom of the plenum?

You cannot replace those lines, you can just replace the whole injector.

Replace the injector or do NOT replace the injector.

Those are your two choices, you pick.
