I'm getting some sediment from my '41 Ford gas tank, and it's clogging my inline fuel filter ever few months. I've read what is involved in pulling the tank, and that seems to be a real headache at best. If I have a drain plug, I'll empty it that way. perhaps I can pour some miuratic acid down the filler, and blow compressed air in it for a while, then drain that, pour some gas down it, and drain it again. Then blow out the fuel line. Whatcha think?
