Hello, I have a 89 b2150dt I just repaired a fuel system problem due to trash in the line from tank . The inside of the tank has a small amount of rust showing . It also looks as if someone sealed the inside of the tank at some point .There are a few spots inside that have came off, thus creating what I think is my trash problem . I have searched for a while with no luck for a replacement tank . My local dealer told me that I may be able to locate a plastic one to do away with the metal one .Funny thing is no one there could locate a metal one for me .If anyone has any information on a new metal or plastic tank please let me know. Thanks to all that may be able to help with this.
