For ongoing, permanent protection fuel needs to pass through a PureFuel Conditioner at least once every 28 days.
PureFuel Conditioners are fitted in suction lines immediately after the outlet of the fuel tank, and ahead of any other devices such as particulate filters, pumps and meters. in certain particularly dirty applications it is prudent to have a strainer-type filter ahead of the Conditioner.
In a recirculating system (most modern engines have a return line from the fuel injection to the tank) this condition is easily met. These are the easiest systems to protect - microbial contamination cannot take hold with a PureFuel Conditioner in the loop.
In a non-recirculating system a PureFuel Conditioner at the tank outlet will, at all times, protect whatever lies downstream - filters, engines, customer fuel tanks and so on.
For fuel storage applications, protection of the tank inlet with a PureFuel Conditioner will stop contamination entering the tank.
A PureFuel Conditioner on the outlet ensures that all fuel drawn from the tank is free from microbial contamination.
