Does anyone have any info on rollover valves to fit 3/8 pipe thds.?


Thanks Rich

I have one that came in my American Tank Aux tank - is a 3/8" fitting with internal rollover valve and a 90-degree 3/8" hose barb. Top is stamped: "TEMCO 90-02622"

It's a fuel tank vent (off my aux tank) that is a safety feature. It vents normally when vertical, but if inverted (as in a rollover), a ball bearing and nylon slug gravity close it off to prevent fuel from spilling out the vent line.
