Ed,
Good timing... I am in the process of installing a fuel cell in place of the 20-gallon aluminum tank. It has been on the chassis for a few months but never been used. Here is shot of the tank:
All mounting hardware, hoses, straps and sending unit also included (same as E-M sold it) I am also replacing the fuel pump (lines and mounting hardware) that was never used if you are interested in that as well.
There are more pictures on my site:
