The side pic shows the filler neck sticking out the drivers side. The pic of the rear heater shows the switch from front to rear tanks. It looks like it was installed several years ago. I bought the cruiser from a guy who bought a house and the cruiser came with the house. He had no interest in the cruiser so he put it up for sale. So not being the original owner, he has no idea about the history of it. I'm trying to track down the previous owner. I have yet to fill the tank and see if it works. Any info would be appreciated.
