Fuel Polishing Products

Dieselcraft Mobile or Fixed FPS systems use the propriety Filter-Less Purifier and MF Stabilizer to remove 99% of water and solid contaminates without the use of filters. The following are standard models that are sized to polish fuel from small tanks to large storage tanks. If you require different flow rates, we have non-standard designs.

FPS HC 15 420 Gallons / 1/2 hr. *Pump has 30 minute duty cycle.
FPS 400 420 GPH Most popular. Good for outdoor/indoor 500 GPH When a gear pump is preferred
FPS 30 1800 GPH Ideal for large volume polishing 24/7

The MF Stabilizer

This disperses and destroys sludge forming agglomerated microorganisms. The overall effect is pre-cleaning the fuel so that the primary filters last longer and become more efficient. It also reduces maintenance-related issues and fuel-related downtime and protects injectors.
