ok so i'm putting a brand new fuel tank on the car and haven't dropped the old one yet but I can't see me using the old sending unit especially since my supplier can get me one for $50
there is the 5/16 and the 3/8 unit though.
Currently it's a 283 with a 2 bbl but i'm putting the qjet on it and who knows what else in the future. Should I go for the larger one or will I run into issues? Also was going to replace the fuel lines complete as well because i'm fussy that way.
