Hi there, I am in need of a solution to fix a rust problem in my fuel tank of my resto car. I haven't actually looked closely at the tank or pulled it out yet, but am trying to get the car running to examine it for a rehaul (see what needs to be done) and would like to have it running decently before i pull it so i know what needs doing to it. I looked in the carbs (S.U carbs) and in the float chambers, there is chunks of cr@p and dirt, etc. Also, the fuel coming out of the line before the engine is murky as well. My question is how should i go about this problem. Has anyone ever used a tank linig kit as shown in link, and if so, do these work well?
Any help regarding this issue will be greatly appreciated.

Thanks in advance!
