carb parts
I don't know what size engine you have but I have a 170 in my 65 pickup and I bought a rebuilt carb from advanced auto parts. The part number is c808 rebult by a company called autoline it cost me 136.00. I put it on and only had to adjust the air screw a little and it runs great. I don't think that there is any aftermarket gas tanks out there but I may be wrong.
