This is what we found inside after the tank went through our boil out tank. That is tank liner coming off in sheets plugging up the fuel system. Also the outside was full of bondo (no wonder it looked so good!)
This is a shot inside the tank itself the brownish white is the liner peeling away from the tanks inner surface (this would not have happened if this was done by a professional and had been cleaned and prepped properly). This is a white variety of tank liner that sells over the counter and that leads me to believe this tank was done by a novice.
We used thick material for this build 12gauge. After the tank has been welded together and pressure tested we lined it to keep the rust out.
And here we have the finished tank ready for install. Please if you are thinking of getting your gas tank cleaned and lined don't try to do it yourself it will cost you money in the long run. We don't line tanks unless we have to and a lot of tanks don't really need lining, only a qualified person who has experience in tank restoration can make that call.
If you have any questions or need help with your fuel system please give us a call we are always glad to help. David
