IPI Industries' B.E.R.G. (Breeze Extended Run Generator System) Systems are made with Aerospace grade material that will not be damaged by gas, freeze in the cold or fade in the sun. It has a flexible hose and all of its systems have a very easy, non-invasive set-up. Each system keeps your generators running for an extended period of time. You can use your own gas tank of any size to keep it running for a longer or shorter period of time, the tank just needs a drop tube. B.E.R.G. II Dual System hooks up to the same generators as the Single Systems. Instead of one generator, you are able to hook up to two, using the T-fitting, creating double the power. B.E.R.G. II Dual Systems include a 6 Gal. Attwood gas tank, hose assembly, cap assembly and a T-fitting. This system can run up to 36 hours without refueling. Single to Dual Conversion Kits are also available for purchase. Compatible brands for Single and Dual B.E.R.G.
