Cp3 differences

I have searched, and tried looking up photos to determine whaqt I need, but no luck. Lbz/Lmm Cp3 vs. 6.7 cummins? What are the differences? Does the 6.7 have the better support bearing like the duramax pump? What about high pressure outlet location? I have a PPE Dual Fueler kit, that calls for a lbz top pump. how much trouble to switch to a cummins top pump? I'm not fond of the 2 into 1 rail feed, so will likely change it. I will also custom make the low pressure/return lines. Where is a good place to have a new high pressure line made if needed? Thanks

Exergy performance can make custom bent lines. Contact them for line availability. They will need a template made out of 5/16th brake line.
