& Diesel

Discover more about diesel storage and diesel behavior as well as why DQTube is designed to solve exactly what is valuable for diesel operations.  Unleash the power to optimize diesel quality and maximize tank conditions with reliable products and experienced expertise.

The design of DQTube maximizes the ability for the Diesel Quality Technology which is inside the DQTube to extract, capture and hold water as well as particles that are removed from the fuel and the fuel tank.


While the primary function of DQTube is to capture water & particles before they accumulate and metastasize, the Diesel Quality Technology inside the DQTube can also separate water and particles from diesel fuel without affecting the fuel chemistry.  

DQTube Installation, Inspection & Replacement Best Practices

The 4 pillars of optimal DQTube maintenance:

DQTube instructions lead to optimal DQTube performance:

  1. Remove DQTube from package and disperse powder evenly throughout the DQTube.
  2. Insert DQTube through the tank opening to the bottom
    of the tank.  If possible, allow DQTube Universal to rest on the outer edge of the fuel tank.  If you need additional string to place DQTube Universal in the optimal position, add nylon string to the end of the provided string.
  3. Secure the string under the opening or close the opening cover on the string leaving as little slack as possible for the DQTube to be lying flat on the tank boom directly under the opening.
  4. Check DQTube at least once per month and replace every 3 months or when DQTube is nearly full, whichever comes first. (When checking DQTube, loosen & evenly disperse the DQTube contents before re-installing back into the tank, for best results.)
  5. Dispose of DQTube exactly as you would a fuel filter.
  6. Immediately replace DQTube to continue optimizing your fuel quality & maximizing your tank protection.

Why Use DQTube?

Not just an emergency product

DQTube captures moisture & particles in every tank and in. any condition.  Even the cleanest tanks, there is moisture and particulate present that can cause harm to the tank, the fuel system, the injectors and the engine system.

Certain value

Since DQTube captures water & particles by its very nature, and every fuel tank breathes in moisture and particulate, DQTube is destined to provide value.  And even a small amount of capture is worth more than the cost of DQTube.  

You can see the results

Water & contamination capture inside DQTube is easily monitored by visual inspection, so there is no mystery in what the DQTube does for you.  With additives and other filters, you have to guess or convince yourself of their true value.

DQTube Is designed for maximum results

Innovative in-tank Design

The patent-pending shape, structure and permeability of DQTube allows the Diesel Quality Technology inside to capture water and expand freely to be most effective. The shape also allows for maximum capture that will fit into and out of the tank smoothly. Additionally, the design allows DQTube to safely remain in the tank 24/7/365 without affecting with suction line or other in-tank fixtures.

Robust Build-Quality 

The stainless steel skin is made to stand up to the rigors of moving vehicles and equipment during operation

1.5mm Abrasion-resistant string

DQTube uses a thin, super strong and abrasion-resistant string that can easily be closed under the fill cap, tied through the cap chain or fixed anywhere in or around the tank.
