Fuel cell, do you recognize this?

This cell is in a car I just bought and I'm looking for more information on it. Do any of you recognize it, and can you tell me who makes it? I'm going to have to pull it out of the car to be able to put wheelie bars on and want to be able to tell potential buyers more about it. About all I know about it is that it is in the stock location and uses the stock filler neck.

Thanks for any help, Jimmy Burns
