The new 2.5 Gallon Reservoir gives much more range to your methanol injection setup, and is fairly small in size 13l x 9.5h x 7.5w (similar to a very small car battery) and includes mounting straps and an additional 10 feet of tubing. *NOTE* It is recommended that a Solenoid Upgrade (#40060) be used in any application that utilizes a rear of vehicle mounted reservoir. The part number for this item is Snow Performance 40014
