Hello all. I'll keep this brief.

ordered the fuel line kit from Fab9tuning, got it in, finally got ITBs (blasphemy due to forum name) and about to tackle all of this. I am aware the NB1 is returnless and I have questions on how to plan this or map this. Here are my questions:

1. Fuelab 515 series FPR, following instructions and it shows the side ports for the fuel is meant for entering in, the bottom port is to return, but if the nb1 is returnless how do I go about for this? Would I damage the FPR if I route the fuel delivery into the bottom port and feed both the sides to the fuel rail?

2. FM's diagram shows that you would need to remove the fuel pump to remove the FPR inside it and place the adjustable near it. I assume this needs to be removed regardless, this true?

3. How would you route your fuel lines for an NB1 using the fab9tuning kit with the fuelab 515 series FPR?
