TEXT:

I am writing for information regarding D.O.T. standards for fuel system's integrity. We are a company that manufactures an epoxy putty which could be used as a patching material for leaking gas tanks. Our customer wants to market this product for fleet (buses and truck) maintenance, but tell us it must have "DOT approval" to be used on gas tanks.

What I am asking, first of all, is : Is there an approval process for a product which would be used as a permanent or temporary repair for patching gas tanks on buses or trucks? Is so, please send me application material and instructions for this proces s.

Secondly, if such an approval process does exist, what performance standards would our product have to meet so that we could state that it complies with DOT standards for gas tanks on fuel systems integrity? Please send any information you can provide in the way of NHTSA or DOT standards in this area.
