Applies to:

Wildfire Poly Tank Fire Pump (Model OT4-N) and SmokeChaser Chief Fire Backpack (Model 190790).

What causes this:

Customers often ask which firefighting product is which and how the parts fit together. Here is a quick reference.

How to fix it:

  1. The Wildfire Poly Tank Fire Pump (OT4-N) is a 5.5-gallon poly-tank backpack for water and water/foam fire retardants. Its hand-operated piston pump fills on the out-stroke and discharges on the in-stroke.
  2. The SmokeChaser Chief (190790) is a fire backpack for water and water/foam retardants. It uses the FEDCO FPG100 fire pump and has a polyurethane liner inside the backpack for liquid containment.
  3. Both are for water and fire-suppressant foam only. Never load flammable liquids, caustics, acids, hot water, or any non-water chemicals.
  4. For replacement parts or service on either product, call 1-800-311-9903 or email info@thefgi.com.
