I was told by several back when I did power tour back in '09 and 10 that my driving a carbureted car with an $18 mechanical fuel pump was the best thing I could have had on such a long trip ..... I had no issues.
The car I drove in, still has it's lean burn on it to this day, also surprisingly gave me no issues then, though now is starting to flake out on me..... This spring that will be going away
Been there since 78 though.
