Fuel Polishing vs. Fuel Replacement: Which Makes Sense?

Posted by

Contaminated diesel does not automatically need to be discarded. But fuel polishing cannot fix every problem. The right decision depends on the fuel’s condition, the type of contamination, and the total cost of getting your tank back into service. Before paying to replace an entire tank—or attempting to salvage it—find out what you are dealing… Read more »

Stored Diesel Fuel: 5 Contamination Warning Signs | Dieselcraft

Posted by

Your tank may be full, but is the fuel ready to do its job? Diesel stored for standby generators, farm equipment, boats, and fleet operations needs regular attention. Water and contaminants can accumulate while the equipment sits idle. Problems may only become apparent when filters plug or an engine struggles to run. Watch for these… Read more »

Coalescer Technology: What Works and What Fails in the Field

Condensed Technical Analysis: Coalescer Claims vs. Dieselcraft Fuel Purifier Hydrophilic coalescer membranes do attract water and allow diesel to pass, causing droplets to merge and fall out by gravity. But they only remove free and emulsified water — not dissolved water. The widely advertised “99.99% water removal” is a marketing claim, not a field verified… Read more »

Diesel Tank Water Absorbers: Protect Your Fuel and Engine

Posted by

A diesel tank water absorber is a simple, passive device placed inside a fuel tank to physically soak up and trap water so it can’t mix with your diesel, cause corrosion, or damage injectors. Think of it as a specialized absorbent “sponge” engineered to capture a specific amount of water and then be removed and… Read more »

Problems Caused by Water in Diesel Fuel and How to Prevent Them

Posted by

Water is widely regarded as the #1 enemy of diesel systems. Even small amounts—especially free water—trigger a destructive chain reaction that affects tanks, fuel lines, pumps, injectors, and the engine itself. In essence, water doesn’t just sit harmlessly—it creates a snowball effect of degradation, especially in stored, standby, or infrequently used systems (generators, marine vessels,… Read more »

WARNING: Fuel Problem – Algae in the Tank and Plugged Filters!

Posted by

**Key Issues to Address** Microbial colonies can be a significant threat in fuel tanks. They thrive when fuel and water coexist, leading to contamination and tank deterioration. Factors like warm weather and increased biofuel use worsen this risk. Once established, these colonies can consume up to 1% of your fuel investment, causing considerable losses. **Understanding… Read more »

Diesel fuel begins to degrade in less than 30 days in your storage tanks.

Posted by

Fuel degradation in storage tanks is a significant concern for industries relying on stored fuel, such as transportation, agriculture, construction, and backup power generation. Several factors contribute to fuel degradation over time, including: To mitigate fuel degradation in storage tanks, it’s essential to implement preventive measures such as: By addressing these factors and implementing proactive… Read more »

What is Fuel Polishing?

Posted by

Fuel polishing is a process that involves filtering and purifying stored fuel to remove contaminants, water, and sediments that may have accumulated over time. It is commonly used for diesel fuel and other types of stored fuels to ensure their quality, maintain optimal performance, and prevent damage to engines or equipment. Fuel polishing is particularly… Read more »

Protect Your Stored Diesel Fuel: Prevent Contamination and Engine Damage

Posted by

Protecting Stored Diesel Fuel from Contamination Diesel fuel starts to degrade and become contaminated within 28 days of storage. Typically, fuel can be stored 6–12 months, but without proper care, its quality will decline. To maximize storage life, many companies recommend: According to NFPA 110, diesel “Storage Life” is 1.5 to 2 years. Tanks should… Read more »
