F.A.Q  DQTube

The DQTube is an evolution of the Aquafighter technology. 

Rather than holdinhg the active crystals in a flexible membrane, the DQTube holds the crystals in a rigid cage which remains inside the tank, where it captures and isolates condensation, dirt, dust, rust and other contaminants.

The smallest DQTube will absorb 400mls of water, whilst the largest will absorb up to 12Lof water

In almost all cases, using the DQTube will absorb the water and contaminants that degrade fuel and tanks., and will prevent Diesel Bug.

In case of a severe diesel bug problem, a treatment with a Biocide may help clear the infestation, after which the DQTube will maintaini the fuel quality.

Additives do affect the fuel quality, and can cause secondary issues. It's hard to know how much additive to use, and how long the treatment will last.

With the DQTube, it's a leave-in-tank solution, that can be inspected at any time to check it's activity.

The DQTube will continue to absorb water and contaminants right up until the crystals and are fully saturated.

A visual check will easily let you know if the Tube needs replacing. The amount of water absorbed can also be determined by weighing the Tube before and after insertion.

The more heaviliy contaminated the fuel, the more often the Tube will need to be replaced.

The DQTubes are inexpensive, with the smallest unit costing under $100.

This will replace additives of similar or greater cost, and will prevent the need for fuel polishing.

A DQTube (or Aquafighter) is cheap insurance to protect all diesel powered engines.
