The “Black” Max Flow chamber is designed for METEOR bodies , replace the original “red” chamber to increase air flow and lower operating pressure , a must have to install a low pressure valve
!!!!! this Chamber is designed to work for semi auto front block or any Pre2K pump kit , will not work with METEOR pump kit !!!!!
secured in place by 1/4-28 VASA screw (different from original “Red” chamber using Metric 6mm screw)
Some older METEOR bodies will need enlarging VASA screw hole with a 1/4 drill (see reference draing) in order to install
