Multiple check valves are commonly used within a fuel cell collector box to protect against fuel slosh. The check valve functions similar to a trap door and keeps fuel contained in the collector box no matter what direction the vehicle is shifting. HERE is a perfect example of a collector box.

The check valves feature a large 1" ball for maximum flow. The 2 piece housing is machined from 6061 aluminum and anodized for corrosion resistance. Unlike round drilled hole variations, this design features full travel slots to prevent the ball from getting stuck in a hole and to promote quick filling. All materials are compatible to be used in gasoline and all alcohol blends such as E85.

The mounting material must be less than 1/4" thick and requires a 1-1/8" hole.

• Anodized Aluminum Check Valve Bushing
• Anodized Aluminum Check Valve Body
