Sounds like you two still need gas tank help. My ’62 gas tank leaked when it was filled. Could always smell gas until the tank was down to 1/2 full. Never saw any leaking gas on ground. During 2006 rebuild of this Jetfire, I took tank out and could not find leak myself. Took to a nation wide commercial service, Gas Tank Renu USA gastankrenu.com/
They estimated $150 for the repair and seal coating job. They had the tank 1 week and the final bill came to $208.15 with a new sender gasket and fuel tube pick-up sock (filter). I was not real happy with the price, but they did the job! No leaks or odor of gas anytime for the past 5 years!
Not quite sure just what “blown-up” means. If there is still a “tank” to work with, maybe the could fix? They do list 3 locations in Illinois. Don’t see any in Kansas though.
