Fuel Pressure Regulator Vacuum Tube, Duramax | 2011 - 2016

This fuel pressure regulator vacuum tube, GM part number 12624346, is the factory-formed tube that connects to the fuel pressure regulator on 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L LML Duramax. The tube is part of the regulator's low-pressure fuel circuit. Engine heat and age can make it brittle, and a cracked or leaking tube can upset fuel pressure regulation and cause rough running, hard starts or fuel pressure codes. It is good practice to replace related hoses and tubes during fuel system service.
