AN Fitting / Fuel return?
What size line do I need to run a fuel rail return line?
I found some 1/4 braided very reasonable, but don't know if that is too small? Will AN-6 fitting work on that or do they require a bigger diameter?

Most use 6 for the return including myself. I run a RSI dual pumper intank with two 6s out into a 8 which goes back into 2 6s into the rails. The rails feed two 6s into the regulator and then the return from the regulator is a 6 back to the tank.
