BMS 3 Gallon Stealth Tank for F chassis BMW

3 Gallon Stealth Tank for F Chassis BMW hides under the deck in your trunk!

Our newest offering, this completely custom design fits in the hidden trunk cavity found in 2013+ F3X and 2015+ F8X chassis vehicles. The WMI pump mounts directly to the bottom of the tank allowing for a quick and clean installation. The bottom of the tank includes a sump and baffle allowing for consistent performance even as the tank drains. Includes 2-way vented black plastic cap and a compression pump feed fitting. Upgraded billet lid with 1-way check valve available.

Optional upgraded blue billet lid with 1-way check valve available here.

The nozzles are determined by the intended power and how many bungs your charge pipe has. The nozzles are 1/8” NPT and screw into bungs included on most aftermarket charge pipes. Our BMS "super atomizing" nozzles are well known for their great atomization and flow characteristics. The nozzle number represents the approximate gallons per hour of fluid when at full flow. Generally speaking, running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution. Below are some general nozzle suggestions but feel free to email us for nozzle advice if your situation is unique.
