Harmon Racing Cells In Tank Fuel Discriminator And Rollover Check Valve With 1" Inlet

Discriminator valves prevent fuel from traveling up the vent line during filling when the tank is full. Utilizing a float, the valve shuts off air flow when fuel enters the chamber. The valve also operates independently and will close/shut off if overturned regardless if there is fuel in the chamber. Because of its ability to prevent fuel from traveling up the vent line and out the vehicle these have become popular on vehicles utilizing dry break and pressurized fill systems.

This particular valve bolts directly into your fill plate. You'll need to drill a 1-1/4" hole. The bottom has a steel ball acting as a roll over valve.

Note: It's always a good idea to run a filter at the end of your vent line. For example K&N 62-1080 listed below. Obviously, do not stick the filter directly onto your discriminator valve.
