I used one of their tanks on a 2188 since 1999 or 2000 and it works great. I found the best way to use it was to keep the valve to it closed until you need it. Many days it wouldn't be needed and then I didn't have to fill it. If I got below 1_4 tank and knew I would be going for a while then I would open it. If you leave the valve open, it will drain before the factory tank and start letting air in to the system. Scares you when engine starts to miss and sputter for no reason. It took me about 2 hours to install by myself.
