If An-6 is the same size as 1/2" then use it...we ran a 1/2" aluminum line from Holley big blue pump to gas log for a 440 six pack set up and then ran a 1/4" return line back to the sump...it was very noisy before we ran the return line

Thanx Bremereric.
The#6 is 3/8 and I think it's to small...JIM.
