Would there be any problem running a 3/8" feed line and a 1/4" return? I'm replacing the feed line and return line on my 95gt since they were open to the humid gulf coast air for about 6 years. I'm also upgrading to -AN fittings and SS hoses to replace stock nylon hoses. I figure I'll just flush the vapor line out with some Seafoam and blow it out with a air compressor. Instead of staying with the stock 5/16" line diameter I wanted to go to 3/8" so I wouldn't have to get a buch of -6AN-5/16" adaptors. I'm running a Walboro 255lph in case I throw a turbo on at some point. For now though stock power levels, stock injectors, and stock regulator. Thanks for any help or thoughts on this. I could run a -6AN return line I figure if I need more flow in the return side and just have both the same size. I could then reduce down to -4AN at the tank with a -4AN to -6AN fitting.
