Depending on co$t, the one in TEXAS might be your best way to go .

Since you've not said where you're at the repair replies might not be most accurate .

In any case, only welded repairs should ever be made to fuel tanks .

If the $20 used tank isn't too bad (I had to use a punched tank in a 1976 GMC truck, the holes were huge yet easily repaired for $35 by a Welder), buy it and take it to a competent Welder, you'll know the competent one because he'll look at it and say 'no problem, cost $X' and do it the same day if not while you wait .

This is where you live comes in ~ in NYC you'll have to hunt a bit, in any outlying area in any state in America, you head to the Weld shop that does mufflers or fences, or Farm repairs, places like that that will have the proper experience and won't think a moment about how to properly and SAFELY weld a fuel tank .

As to how to repair it, take the junk tank too and ask him to use a bit of it's metal to gusset over the punched holes, simple, easy and cheap repair that takes less than 1/2 hour .

Don't forget to spray some glossy black Rustoleum paint over the repair when you get it home .
