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

This particular valve bolts directly into your fill plate. Discriminator valves prevent fuel from traveling up the vent line. There are two balls in a discriminator valve. One ball floats when fuel enters the valve. This is especially important if you're using a pressurized fill system. The other ball is heavy and uses gravity if you roll the vehicle over.

It's always a good idea to run a filter at the end of your vent line. For example K&N's 62-1040, 62-1130, 62-1080 or 62-1170. Obviously, do not stick the filter directly onto your discriminator valve.

Dimensions:
• Length Tip To Tip: 7-3/4"
• Depth Inside Tank: 2-3/4"
• Diameter: 2-1/4"
• Inlet: 1"

All of Harmon's discriminator valves are available in raw aluminum, clear anodized aluminum or black anodized aluminum. The raw aluminum valves allow you to tig weld the housing to something without having to grind off the anodizing prior to welding.
