This site is dedicated to educating about Diesel storage & our DQTube Solutions

Discover more about diesel storage and diesel behavior as well as why DQTube is designed to solve exactly what is the valuable.  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 advice

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.

Guaranteed 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.
