Is that for running twin 044 pumps?

These are all An-8 line (1/2") Under 7 bar of pressure, you can pump a gallon in a few seconds. I doubt you will need more fuel than that. My fuel pressure rail is set to 5 bar. I can use 1 pump and maintain that with my K29/K27 turbo running 1.45 bar.

Would i need the same size for a return?

[james_bufkin]

yes because its a closed system and at idle you aren't using much fuel

So what power will the stock ones flow?
