THIS IS A FUEL FILTER TO REPLACE THE OEM FUEL FILTER ON THE PATRIOT BOOST TO RELIEVE THE THE PUMP.  THIS FILTER ALOWS MORE FUEL FLOW, YET STILL PROTECTING YOUR FUEL SYSTEM FROM UNWANTED PARTICLES.  THE REASON THESE FUEL PUMPS ARE FAILING AND ARE MAKING NOISE IS BEACAUSE THE FILTER IS TO FINE AND DOSE NOT ALLOW ENOUGH FUEL TO THE PUMP AND IS STARVING IT, CAUSING LOW FUEL PRESSURE AND ULTIMATLEY IN TIME RUINING THE PUMP.  REQUIRES 2 FILTERS FOR EACH MACHINE.
