Ok, I just found out this morning my gas tank has a small leak at the seam. Is there a way to fix this? This is the 5 horse I just got on the David Bradley and I was just wondering if there was a quick fix I could try.

You have a number of options. Solder, Epoxy, or a liquid liner in the tank. I've had limited success with epoxy. I'll try the liquid liner this spring on 5 tanks that I've got. Good Luck, Rick

If its metal and we are talking a small leak (seep), I would try the liner. You'll have a couple of days with dry time, but I think it will be your best bet. What ever brand, read and follow the directions exactly.

Please let us know if you try the liner. That is what I would use but I have not had the chance to try it yet.  Good luck Rick!

Many, Many, Many moons ago when I was a teen, a friend of mine had a small leak in his gas tank on his car.  An old timer told us to use bar soap as a temp fix.  It worked, every 4 or 5 days he would get under his car and scrap some soap over the hole.  


A more permanent fix would be as stated above, but if you just need a quick temp fix the soap may help.

I love the soap idea.  That goes in my book of great makeshift ideas to have when I need it!  You have to snatch that knowledge from the old timers before they go.


I used Eastwood's sealer on my Farmall tractor tank.  It will produce much more than you need for a Bradley, though.  Maybe you could seal a couple others while you are at it!


Try a radiator shop: my local one sealed a few Gravely tanks for me very cheaply.  He even painted it!

I believe I would also take the tank to the radiator shop, I read a sign once on the building of a radiator shop that read 'the best place in town to a leak'.

I have had good luck with the gas tank sealer you can by at the auto parts house. Its about .5 in. dia. and abou 3in. long. also beleave it or not, Bondo works well. Just make sure the surface is clean.

If the tank is clean inside, solder would do the trick, if its rusty, I would try RedKote to seal it.
