Testing pressure regulator valve bores with the Sonnax vacuum tool. I adapted my AC machine to use the vacuum pump. The fixture gets calibrated. And then the testing begins. The reamer will be here tomorrow, then we can see how much improvement can be made. Remember these are all cold tests. Once the pump warms up the aluminum will expand greater than steel PR valve and it will open up even more. One pump tested at 18 inch. 3 or 4 tested close. Most where 14 to 15 range. #stevevsautomotive #gran

The best way to address GM 6L45, 6L50, 6L80 and 6L90 pressure regulator valve problems is by replacing a wear-prone OE valve with an improved #Sonnax drop-in Zip Valve™ or oversized part. Installation requires drilling a small hole in the pump, though, to prevent excessive line pressure. Learn more about why drilling is necessary and watch the simple, step-by-step process in this quick video.
