So I got this 32 year old Cigarette Top Gun and at least one fuel tank is leaking. I´m in a Third World country and cannot rely on local knowledge, I must give clear instructions and I hope I can get some information here.
Questions:
1. Each tank holds aprox 120 gallons and is 8"5´ long. With this size should I choose 3/16 or is 1/8 enough?
2. Which aluminium is best suited for this? 5052 or 5083?
3. How many baffles are needed on this length?
4. Any other suggestion?
Any info would be great and thanks in advance
