The fuel tank needed a good cleaning. I used some rust remover in the tank. I also put in a short piece of chain and taped the openings shut. I rotated the tank around in all directions and let it sit for a couple days. After that, I rinsed it out with water and let it dry. After it was dry I used some Red-Kote fuel tank liner. I rotated it all around to coat the whole interior. I then turned it upside down to drain out the excess and let it dry. I think it worked out pretty good. I didn't have any problems with it plugging the fuel line outlet.
