I installed a longranger tank from the address in the previous post in 1999 on my 2188. It is an excellent product. I installed it myself in about 3 hours and have never had a problem with it. With it we have never run out of fuel in a day even going from 9:00 am to 1:00 am. Before we usually had to pump some in around 8:00 pm to finish the night. Rod
