Leaking Gs 1100 tank ,then I really made it bad..

[Devilwinner]

Got a great '81 Gs1100 . Filled it up ,parked it the driveway . Got a call half an hour later telling me that gas was leaking all over. Turns out it was leaking from where it bolts down close to the seat. Chapter 2 - The tank had been repainted , the paint was all cracked and chipped and looked lousy , so i decide to dust it with my sandblaster and re-paint. All is going good until I see some moisture seepage. Oh yeah I opened up a few pin sized holes along the bottom seam. I am mad at myself for even trying now but i really was going easy or so i thought. Is there any hope of saving this tank ???

Yes you can save this tank but it will take a little work on your part.

You will need to do the Kreem thing (it will seal up little pin holes) but first you need to evaluate the extent of the rust damage and clean it all off and patch with fiber glass and resin.

I had the same situation with my 1981 Honda CB650 Custom, al lot of rust holes. I striped the paint off using paint stripper then power washed the inside of the tank to remove all of the loose rust. Part of the Kreem kit is an acid to remove all of the stuck on rust. I had so many holes in the tank I used a large plastic tub to put the tank in as it would not hold any fluid without leaking.

After you have used the kit, let it dry and cure for two or three days. Now the fun begins. Go to Ace Hardware (or whatever your local hardware supplier is) and purchase a fiber glass repair kit. Inside the kit is glass cloth, resin, and hardener. Follow the directions and patch the areas that were leaking before. Sand these area smooth and repaint. From start to finish it should take about a week. You will end up with a good looking and non-leaking tank.

I suspect that you are going to find that the places that are leaking are just the few that have rusted all the way through, and that it is perrty thin in many other places along the bottom of the tank.

Thanks for the info .I will get to work on it .

I've heard of the Kreem® brand and it's probably quite good. I have personally used the POR-15 tank sealer kit and it's phenomenal. The same logic applies... pressure wash out the rust thoroughly and treat the inside with the acid treatment to finish dissolving rust and follow the steps in the instructions. The POR-15 kit will actually plug pinholes without any external patching being necessary. If larger holes are there, fiberglass or an epoxy patch will be required in either case.

Go with the POR

Used both the Kreem and the POR, go with the POR. Follow the instructions to the letter and it will last a long time. Good Luck

If the tank is ok on the inside (no rust), I would consider soldering the seam. Use a LARGE soldering iron, not a torch.

Wow ,what a find . My GS is a '81. Tanks look the same . But... if you think it will work I will bid on it right now.

I used the POR-15 motorcycle kit myself with great results. The kit I used actually came with some thin cloth to patch larger holes if needed, mine needed it. Going on my third season since the repair and it's still holding fuel. Assuming the the holes are on the bottom out of sight you can just paint over the POR-15 patch so it's not too obvious. Just allow plenty of time for the prep stages to dry properly before using the coating.

Does anyone know if a 1980 GS1100 tank will fit on my '81 ?
