The P510MAM Fuel Polisher removes fuel contaminates directly from your fuel tank before they can reach your fuel filters.
A surprising amount of water, rust flakes, and particulate matter can enter your tank during refueling.
Typical onboard fuel filtration systems capture this contamination as the fuel flows through 2 or 3 filters on the way to your engine.
With a load of poor quality fuel, filters often clog prematurely which can lead to inadequate fuel delivery, increased emissions, and potential expensive damage to injectors. Refining the fuel before it reaches these filters ensures they work at peak performance throughout their service life.

The P510MAM contains its own internal fuel pump. By setting up a separate, off-line recirculating circuit - out of and back into the tank - the P510 Polisher removes water, dirt, algae, and rust from the fuel before it gets to your regular filters. This means longer filter life and less unscheduled downtime to change clogged elements.
The P510MAM Polisher is used in marine, agricultural, over-the-road, off-highway, construction, oil and mining, and power generation installations.

Heavy on the technical side...
Note - Depending on how it is plumbed, the P510MAM Polisher can also be used as a Secondary Fuel Filter, or for Fuel Transfer between tanks, using its integrated pump (see Installation Instructions for details).

How does all that stuff get in there?
Water is most often introduced into the tank during refueling, if the source tank is contaminated with water.
Water can also enter fuel tanks when moist air is drawn into the tank through the vent hose as the air in the tank cools and decreases in volume during the night, or when the engine is shut off. The moisture in that air may condense on the sides of the tank, and eventually collect in the bottom of the tank as liquid water.
Bio-fuels and fuel treatments and additives can loosen existing deposits on the inside of the tank.
Contaminants and debris can be introduced into the tank during refueling.
