For fuel filters, you could really just use any name brand...Purolator, Fram, AC Delco, Wix, etc.
I think what would really be nice is one of those feed lines that attaches to the carb, makes a 90 and then comes straight to the front.

You can get all the same stuff in either chrome/silver or black if you want as well. With the way rubber fuel line gets hard and cracks today, I try to keep as little as possible in the system.
Really like this build.
