If you need to do some repairs to the tank, I can recommend a product called Plasti-mend. I used it to repair a cracked tank and believe that portion of the tank will never be a problem again. I bought it online after a google search.
This forum is full of good people who have saved me thousands of $ over many years of reading. My thanks to all of them, and good luck to you as you begin your new adventure, HarveyP
