I did the tank for my '59 Austin Healey myself using the method described. The secret is to use the right tank sealer. Find Bill Hirsch's sealer, a few companies sell it, Bill even sells it direct from the web. It is by far the best I've found and it will handle ethanol no problem. The FC should be really easy since you can remove the pump and pick up.
