This is an empty replacement bottle only for the FireCharger 2.3L AFFF Fire System (Part No. 2018). If your bottle has been damaged, you can get your system back together with this bottle and a FireCharger Refill Kit (Part No. 2025-2.3, sold separately).
The New Style bottle was introduced in spring of 2005. The major change is the introduction of a cover over the actuator to prevent snags and accidental actuation. The new style bottle can replace an old style bottle without any modifications required.
