BMS offers a variety of water methanol (WMI) tanks, both for universal use, and vehicle specific fitment. Our most popular tank options are the 1.25 gallon universal, and the 2 gallon universal. The 1.25g is meant to be mounted against a flat surface with the pump mounted below, while the 2g can be mounted anywhere in the trunk and includes an integrated pump mount and baffle providing a very clean easy to install package. We also offer several BMW application specific tanks as shown below.
The Burger Motorsports 1.25 gallon heavy-duty tank is compact and flexible allowing for a wide range of mounting on any flat vertical surface in the trunk.
This tank is thicker and stronger than the basic 1-gallon WMI tank. This tank features an easy fill filler nozzle, an anti-starvation reservoir with a pre-threaded bung for the included 90º compression pump feed fitting, a spill-catcher reservoir around the filler cap, a 2-way vented black plastic cap, and is translucent to allow visually checking the fluid level.
