I bought this 1958 tr3 with the fuel shut off and two piece fuel line with solid connecting plumbing back in the 70’s with sugar in the gas tank, and now I am thinking of using the fuel lines. I remember the corner gas station guy that knew everything (and really did) told me to flush the tank and lines out with hot water and things would be fine. I pulled the tank and flushed it many years ago and it was fine, but did not do the lines. Now with the lines off, I am thinking hot water with a funnel then blow some air through then maybe some WD40 and more air and maybe a paper filter up in the line right before the hardline goes into the braided line. Not sure what sugar does and not sure if a filter would catch deluded sugar or what and suggestions?
