Dieselcraft Fluid Engineering Div of Magnum Group

Fuel Polishing and oil cleaning technology business since 2002. Expertise to reduce operating costs and fix your problem. Quick, simple and low cost Fuel Test Kits to help diagnose fuel problems. The key distinction across all Dieselcraft Fuel Polishing Systems products lies in the "filtration process," which begins with the Filter-Less Purifier. This innovative system removes 99% of water and 95% of solid contaminants on the first pass by leveraging our proprietary process. Using the principle of specific gravity, it efficiently separates heavy particles like water and solid impurities from the lighter diesel fuel. Meaning less filters to buy and lower operating cost. Bypass oil filtration system using an oil centrifuge with no filters to purchase to double your oil life.
