Hemi fuel filter upgrade

I want to run a 3/8" line(to replace the 5/16)line from the filter to the T block on a '71 Hemi to improve fuel flow volume at WOT. The issue is with the stock filter itself as it is 3/8 inlet and 5/16 outlet (with a fuel return line). Does anyone know of a filter that is stock looking that will fit in the stock location that also has a 3/8 outlet with the fuel return line that will allow this?

Anyone out there? How about you stealthy F.A.S.T. guys??
