It all depends on how you're gonna run the line. I'd go with braided hose, at least a short piece from the tank to the filter, and between the filter and pump. Then another short piece up front from the line to the carb.
Fittings... hmmmm. 1 into the filter, 1 out. 1 into the pump, 1 out. Do you have a -AN flaring tool, or can you get your hands on one? I'll throw some tube nuts and stuff in the box when I send it to you, you'll need them to go from the solid tube to the braided hose.
Quick shopping list off the top of my head:
Bulkhead fitting
6 -8 straight hose ends
4 -8 to 3/8" NPT adapters
?? -8 hose
?? 1/2" aluminum tubing
I'll throw some "help" in the box when I send it out to ya.
