What To Do Before Sealing The Gas Tank

But before sealing your gas tank, there is a need to consider first thing first. And that is to clean the gas tank first. You should begin with draining the fuel out and then remove the sending unit as well as filter assemblies and all the associated fittings.

If the tank is already dry, you could knock the surface rust down through the use of a part of the chain as well as slide it around inside the gas tank. Right after the tank dries, you could now use a cleaner and prep agent as for sealing the remaining rust and also to remove the remaining contaminants. The process of applying the product might vary based on the instructions of your chosen product.

Lining The Gas Tank

In lining the gas tank, you must tape over all the holes in the gas tank except the one wherein you will pour the sealer in. Those tanks having less than 12 gallons could be done with a quart, however, those tanks that are larger than 12 gallons would need the additional sealer.

Right after pouring in the gas tank sealer, you should tip the tank back and forth and side to side slowly making sure that there is an even coating within the tank. The excess sealer could be drained and be placed in a container for either disposal or reuse.

It is also advised that you just turn the tank to where the excess would drain out of the opening into a pan. If it’s already drained, you could simply remove the tape from the additional opening ensuring maximum flow of air. And allow the tank to air dry for at least eight to twenty-four hours. If the gas tank has dried, it would be safe for you to reassemble and place back into where it is being used.
