I found about 10 pinholes in a 3"X 3" area and about 4 others where the strap covers it.First I put a bag of sand in the tank and shook it and turned it for about a half hour. Then I cleaned it by shaking it around with water til nothing came out of it any more. The area around the outlet for gas had the cluster so I got a piece to cover that spot and welded a new pipe in the middle and welded the patch on. I then spot welded the remaining pin holes.The bottom and the welded pinholes are not visible so after letting it dry in the sun for an hour, I painted the tank, total cost maybe $15.00 and 2 hrs work. It looks great in the truck and it does not leak. I have to save money any way I can. How much time would it take to arrange and pick up a new one/cost? How much time/cost would you have to invest in another used one? You pick, it all depends on what your needs are,in my case I want to spend my money on my family and home.My truck is just my hobbie and what I like, is doing the work .The second it's finished I will drive it and sell the last one, so I can build another one, that's part of the fun.I usually have a driver and as soon as I finish my project ,I sell the one I drive.
