I just bought a 1968 coupe and am having some issues with sediment in the tank. First night we dropped and drained it - definate rust present - now I'm shopping for a good fuel tank. Any suggestions?? I have come across the "replacement" brand on autopartswarehouse.com and carpartswholesale.com - is this a reliable brand?? Any better ones to consider? I'm a complete newbie at this and any suggestions are much appreciated!!
