Slowly,
I run the exact same system, carter black lift pump and 044 I have the surge pot as in the pick below.
The bottom line is the feed to the 044 which is about 100mm from the end of the filter.
I have had no problems with this and it feeds the 48 pound injectors and maintains the fuel presure at the rails with out a problem.
All hard lines are 1/2 inch and all braid is AN 8.
I am not sure if some one has mentioned this but is your tank vented?
