Fuel Tank Sealer

Many people who have damaged fuel tanks do not want to spend the cash that is required to buy a new fuel tank so they purchase fuel tank sealer. There are a lot of different fuel tank sealer offerings out there, but all of them are used in pretty much the same manner. If you are using a fuel tank sealer you should know that this should always be the last resort to repair your tank, but if you need to seal the fuel tank this is a safe and effective way to get it done.

First things first, you should do this outside and you should start by removing at petcock, the cap, the crossover hoses and anything else that there may be and then seal all of the openings. The only thing that you will want to leave unsealed is the actual fuel inlet. It's important that you take great care not to get the fuel tank sealer on the painted surface of a tank as it may actually remove or damage the paint.

How much fuel tank sealer you will need will really depend on the tank that you are attempting to seal. You should always read the fuel tank sealer directions of the specific brand that you are using but as a general rule of thumb you'll need one pint for one to five gallon tanks, and then one quart of the fuel tank sealer for every 20 gallons of capacity in larger capacity fuel tanks.

For an fuel tank sealer to work you have to be sure that it is completely free of all oil, dust, grease, and gasoline. If these items are present in or on the tank you will have a problem getting the fuel tank sealer to work well. To get started you will need about a pint of a liquid degreaser and you'll put it into the tank and slosh it around with all of the openings capped off. You'll want to do this for at least five to ten minutes, being sure that you tip the tank upside down to allow for the surfaces around the fuel inlet to get washed off properly. If there is a lot of rust or grime inside of the tank put a few nuts and bolts in the tank with the degreaser to loosen the grime from the sides of the tank.

Once you have done this for ten minutes you will need to add very hot water to the tank and then slosh it around again for about five minutes. When you have done this you need to remove the mixture as well as any nuts and bolts that you might have put inside to help with the cleaning process. At this point you are ready to put about a tablespoon of dishwashing soap into the tank with a gallon of hot water and slosh and then rinse until there are not more bubbles coming out.

If you have purchased a kit and it came with a tank prep you will put them into the tank and it will clean and etch the inside of the tank for you. This mixture will generally need to be mixed with water and then sloshed around the inside of the tank for about ten minutes. Then sit the tank down for 15 minutes to let the mixture go to work. After this, pour the mixture out of the tank and rinse. If there is another prep mixture pour this in so that it coats the tank and then pour it out.

At this point pour the entire amount needed of the fuel tank sealer into the tank. Rotate the tank in all directions so you are sure that you get all of the inside surfaces of the tank. Let the tank sit for ten minutes and then move the mixture around again to ensure that all of the surfaces have been adequately covered. Repeat this process several times and then drain any excess fuel tank sealer for later use. Unseal all of the tank openings and allow for the tank to dry for four days.
