Fuel Filter Outlet Hose, Duramax LML | 2011 - 2016

This fuel filter outlet hose, GM part number 12636274, is the low-pressure hose that carries filtered fuel from the fuel filter head outlet toward the CP4 injection pump. It fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L LML Duramax. These rubber hoses dry out with age and heat, and commonly crack near the ends. A cracked hose can seep fuel or let air into the supply, causing hard starts and long cranking, and degrading rubber can shed debris into the fuel system. It is good practice to replace fuel system hoses during filter or pump service.
