If you don't want to rebuild the one in the tank you can get an external one. Try here: http://www.alfaheaven.com/ Here is their product: http://www.alfaheaven.com/MilitarySection/InstFuel.html I have not done this mod but I think you might still need to get in the tank to make...

Well I do have another spare tank but want to try and repair this one first and keep the other one as a spare.

Well it was a nice day here in the south. So I took to sand blasting. Here is the before for the corner and the after. Oh joy, now I have pin holes to repair. Just shows how bad the rust was. Here is where the blasting ended near the baffle. The rest I will blast another day...

If I cut the outside and weld I am not sure I can get the tank to seal. Now I can reach anyplace in the tank.

You are just a few steps ahead of me. I have the same instructions. I have my Phosphoric acid ready, acetone and I plan on using this tank sealer - http://www.hirschauto.com/prodinfo.asp?number=GTS It claims to be alcohol resistant. We will see. I just know with these sealers you need to...

I have given up on the sharp stones and the muratic acid. I have declared total war on the xm211 fuel tank. I got the plasma cutter out and cut the baffles. I will wield them back later. In the photos you can see the rust I can't get out. Next I will use the sand blaster.

This tank I consider safe to wield. I have run so much water and cleaners through it.

I had a thought on the drive home from work. I can get my arm inside the tank where the pump opening is. Instead of cutting a hole in the outside of the tank I could cut a hole in the baffle. Then I could get the sand blasting nozzle in there. Then when it gets nice and clean weld the...

I did use some sharp stones in the tank and strapped it to the forks of my tractor to shake it. Its a 60 gallon tank so its hard to strap to a wheel. The gravel did get a lot of rust but there is just a lot there. Alan

Well it has been a long road working on this fuel tank. Sometime in Jan I bought some molasses and turned the tank on end with the pump and filler opening on the up end. I poured in the molasses and hot water. Then I added enough water to fill the tank so the water level was just at the pump...

Been too busy to work on the tank. I can get my arm inside the tank where the pump mounts. So now I am thinking of cutting holes in the baffle wall and using my re-bar and doing electrolysis on that end of the tank and then laying it down and doing the same on the open end of the tank.

I had time this weekend to work on the fuel pump and tank. I wanted to slide the inner part of the pump housing from the outer part so I could get to the pump. But it would not budge. So I decided to use the torch on it to heat the outside so it would expand. Well all that stuff that looks...

I decided to take the fuel pump assembly apart late this afternoon before the sun went down and it got cold. I took the filter screens off and the pump was totally rusted, so much it was in two pieces. Anyone cleaned the filter screens? What did you use? Alan

Worrying about the rubber mount I took the pump assembly out. The rubber looks fine. There is a number of items rattling around inside the fuel pump housing. I will take that apart another day. The fuel tank is in a shed. Right now its about 35 degrees, rainy and windy so that is all I...

Have to put the tank cleaning on hold as we have had so much rain its a quagmire around the work shop and I have to tote the tank around with a hand truck. I did think about strapping the tank on the forks of the tractor and shaking it really good. I have what I think is an NOS fuel pump...

Yesterday I worked on the tank some more. I had put 3 gallons of lacquer thinner in the tank and sealed it up, sloshed it around and let it sit for 24 hours. I got more rusty looking crud out and since the tank was turned up on the end where the filler cap is I can see a whole pile of crud in...

I have it off now and that is one heavy tank with the pump still in it and all that crud. I now see some rust on the outside that makes me wonder how thin it has become. I know folks have added an external 24 volt fuel pump that works well. If I can get an internal original fuel pump that...

I still have some lye left I might put in there with warm / hot water. Have to be careful with that stuff. Wear gloves, long sleeves and eye protection. I did a smaller tank like that years ago. Not a big monster tank like this. Oh and I do plan on taking the pump assembly out as I am sure...

This latest long weekend I decided to work on the XM211 a bit. So I started killing the rust on the passenger battery ledge. While my solution was doing its job I decided to drain the fuel tank. The previous owner said it was totally full of real gas. Yeah right. So I used a shaker siphon...
