Only as Clean as Your Fuel.
0.5 micron filtration works alongside your factory filter—removing contamination before it reaches injectors and pumps.

The Stakes
You Can't Run a Modern Fuel System on What the Factory Filter Misses.
Common-rail pressure exceeds 30,000 PSI. Injectors and pumps run at micron-scale clearances. Contamination you can't see is already wearing the most expensive parts on your engine—every mile without ultra-fine filtration.

Or Put Thousands Back in Your Pocket.
0.5 micron filtration removes the particles factory filters leave behind. Many operators see 3–20% fuel economy improvements—that adds up fast on every truck you run.
The Problem
What Gets ThroughDoesn't Stay in the Tank.
Water
Moisture can contribute to corrosion, poor lubrication, and injector problems.
Downtime
Fuel-system repairs can take equipment out of service and cost far more than better filtration.
The Solution
Cleaner Fuel Before ItReaches the Engine.
- 1
Fuel Enters the Filter
Fuel flows through your existing system and into the Pure Flow Solutions filter.
- 2
Microscopic Contamination Is Removed
Ultra-fine filtration catches particles factory filters may leave behind.
- 3
Cleaner Fuel Reaches the Engine
Cleaner fuel moves on to your injectors and high-pressure pump—without the restrictions that can rob power and MPG.
Real Proof
Real Fuel. Real Testing.
Independent ISO testing showed a 99.28% reduction in damaging particles before they reached the injectors.

The lower the ISO numbers, the fewer microscopic particles are reaching the engine. Shorter bars mean cleaner fuel—all three channels sit below the OEM target of 18 / 16 / 13.

FAQ
Yes. Contamination that reaches injectors can disrupt spray patterns and force the engine to work harder. Ultra-fine filtration removes particles factory filters leave behind—helping restore efficient combustion. Many fleets see 3–20% fuel economy improvements depending on equipment, fuel source, and operating conditions.
Not when sized correctly. Our 0.5 micron elements are matched to your engine's fuel consumption so the system flows 4–5× what your engine needs under load.
Usually not. Most setups add Pure Flow Solutions filtration alongside your factory filter. In some applications we can replace the OEM filter—we will match the right approach for your equipment.
Tell us what you operate—make, model, and application. We size from your engine's maximum fuel consumption and confirm fitment for your unit.
We recommend changing by operating hours—often every 200 to 500 hours depending on the kit. Each filter kit includes guidance for your application.
Absolutely. Our fuel kits are designed for self-installation—with the right tools and basic mechanical knowledge, many customers install their own. We also support customers with installation, and for several of our customers we sell kits installed. Ask us about either option when you order.
