Review on MEANLIN MEASURE 0-200Psi Stainless Pressure Gauge: High Accuracy and Durability for Precise Measurements by Scott Ward

This vent valve is just what is needed for the correct operation of modern plastic fuel tanks as it supplies air to prevent air from blowing through the fuel tank filler nozzle. Complete with drill, wrench and air valves with locking caps. You'll need a drill motor and a little mechanical knowledge on where to find a new air supply valve. Otherwise, installation will be an easy task. .
