Default Fuel tank clean up.

Has the subject of restoring the inside of a small engine fuel tank come up on the Stak?

I have been using "the works" and it "works" great!

Any other suggestions?

Place nuts-bolts chain pieces etc. in tank. Add water replace cap and seal vent.Wrap the tank in foam rubber with duct tape. Place in clothes dryer when wife not around. Run without heat for several minutes check and rerun if needed.

I use BB's. Then fill it half full of hot water with dawn soap, then bungy cord it inside the wheel of my dually, grab a beer, and drive up and down the driveway real slow.

First I plug any holes. Then I dump in a bunch of old nuts and washers and a couple cups of kerosene. Next I block up one side of my riding mower and strap the tank to the center of the hub. Put the mower in gear and let it spin on idle for a while. Dump out the liquid, add fresh kerosene, and repeat until it comes out pretty clean. Finish it off by washing out super well with a degreaser detergent and dry well. Afterward you can seal it with an epoxy sealer, perhaps POR15 tank sealer. That will prefent future rust and seal up any pin holes.

I just sand blast the inside and this works real good. I many cases the bottom of the tank looks like a screen door when complete. If it happens to be a tank that is hard to find I cut out the bad part and solder in a new piece. The small briggs tanks have a replaceable bottom available from Bobs small engines. This makes the tank like new. With the sandblasting with a good solid tank it does a good job of cleaning. At this point you can seal the inside of the tank. I have never sealed the small engine tanks. I have sealed the larger hit&miss tanks. Also on some of the larger tanks is the ones I have replaced the bottom with new sheet metal.
