Did you find the fix to this problem? My 1986 F150 has the same problem. I've owned the truck for many years, but I don't drive it much and keep it in the garage. It just has 150K miles. Problem first started when I noticed a vacuum release with the front tank when I removed the cap to fill, now tank pressure is so much that gas blows by the new cap. I want to know how to fix this dangerous problem.
