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.
