Step 3: Apply Duct Tape to Any Big Leaks

This first step is optional for those of you whose gas tanks are in decent shape, but for those who are not so lucky it's a good idea to place duct tape over any areas that will leak to avoid losing some fluid.

Step 4: Clean the Inside of the Tank

Begin by removing the tank from the bike and screwing it open. Depending on the type of cleaner being used you may want to make a 1:1 mixture of the tank cleaner fluid and warm water or use the fluid on its own.

Pour the liquid into the tank and slosh it around for 45-60 minutes to get rid of any impurities, debris, or grease.

Allow the cleaning solution to sit in the tank for several hours while continuing to shake regularly.

If you have a very rusty tank feel free to put some nuts and bolts in your tank while sloshing to help release some of the rust.

Step 5: Rinse out the Tank with Water

Dispose of the cleaning fluid and rinse out the tank. Be sure to get any excess fluid out!

Step 6: Apply Rust Remover

This step ensures that any stubborn rust will be kicked out and gives the tank a nice adhesive foundation for the sealer to stick on to.

Begin by placing the funnel in the fuel tank opening and emptying the rust remover container into the tank.

Shake the tank for about 20 minutes to evenly distribute the liquid and then let it sit for several hours and shake occasionally.

Step 7: Rinse & Dry

Thoroughly rinse the tank out with water and dry overnight. Make sure the tank is fully dry before continuing to the next step.

If you're unsure of the tank's dryness use a blow dryer with a fresh filter to dry out the tank and ensure there's no dust.

Step 8: Prepare to Apply Gas Tank Sealer

It is recommended to use rubber gloves or any other protective hand wear while applying the gas tank sealer.

When using Tank Cure Sealer components A and B need to be mixed together before applying the sealer.

Pry the sealer open and stir to get out any air bubbles.

Step 9: Apply Gas Tank Sealer

Use the funnel to pour the recommended amount of sealer into the gas tank.

Rotate the tank several times so the sealer evenly coats all sides and don’t forget to make sure all the cracks and crevices get covered!

Take care to not leave the sealer in for too long or it can clog up screw holes and other small areas that need to be accessible.

Step 10: Dry & Drip

Remove all plugs from tank openings to empty any excess gas tank sealer from the tank and place a drip tray under the tank's opening to catch any leftovers while the tank dries.

Let the tank dry for 96 hours or the recommended time for your sealer.

If you have a tank with a flat surface that may be hard to drain use a hydraulic plunger to drain out any excess sealer.
