I actually wonder more about that tiny 1/4" return to regulate pressure with a high capacity pump more than the ability of the stock 5/16" line to supply it.
Being the regulator is a mechanical device and considering the return is simply un-spent fuel, how does it become a concern?
Let's consider if the rail and or demanded fuel exceeded the supply, the return would be empty - would it not?
Therefore, the fact fuel still returns to the tank indicates supply exceeds demand.
Don't worry about the 1/4" line - it's only there to return what wasn't consumed.
