Brand: Fuel Safe Fuel Cells
This vent fitting mounts in a 3/4" hole in the fill plate of your fuel cell. The built-in check valve stops the flow of fuel in the event of a rollover, but it is not spring-loaded, so it offers virtually no resistance to air coming in. 8AN male fitting allows easy hookup of a -8 AN or 1/2" rubber vent line. Includes mounting nut and sealing washer.
