I have a aluminum fuel tank and it is leaking I am going to take it out this weekend. I called around today and the lowest I could find is $150 if anyone knows some place that does it for less could you please let me know..thanks
If you don't use one of these other guys, let me know. This kind of stuff is routine for our fab shop at work (tank trucks). We're in North Portland, and it would probably have to be done during the week.
Why weld it? Rough up the area with a little emery cloth, dry and degrease the area and get a couple of tubes of JB Weld, mix it up, slather it on, wait for the stuff to harden and you are done. This stuff works! Probably the most important part of the process is cleaning the area. Use acetone or lacquer thinner to clean the area after you have polished and roughed it up with the emery cloth.
If you get the tank welded, be sure to let it drain after you get it back. Before welding the tank is filled with water to displace the fumes. Also, I would suggest a couple of bottles of
"HEAT" to remove the remaining moisture. HEAT can be found at Schucks or NAPA ect.
I had my aluminum gas tank for the boat re-welded at Acme Welding on SE Salmon for $64.50 this spring. Did a good job at a good price. Had me drain it and wash it out with Dawn and hot water a couple of times before I took it to him. I ran a gallon or so of gas in it after I got it back an swished it around and dumped it. Everything came out great. Did it in a couple of days turn-around. Stevens was a three week wait. Hope this helps. E mail me and I will send you the phone number :cheers:
Pretty tough to weld aluminum filled with water. Actually, welding gas tanks is pretty simple, you run an exhaust hose into the tank from a running engine, that creates an inert atmosphere. Weld away. JB Weld might work if you can get the crack clean enough and there is not much flex to the tank. JB doesn't flex well at all. If you use JB and then end up getting it welded, your weldor will not be too please with you 'cause he (or she) is going to have to grind it off. BTW, the best heliarc weldors that I knew were women.
On afterthought, if you are going to weld it yourself, don't do it indoors with CO pumping into the tank. And yes, the tank will need to be degreased, the hot water and Dawn will work. Alumimun needs to be pretty clean before being welded. I'm surprised that you can't get a new tank for some of the costs quoted, but then its been more than 20 years since I made my living welding.
