Fuel Filter Head Bleeder Screw, 2001-2016 GM 6.6L Duramax LB7 LLY LBZ LMM LML

Replace your soft plastic stock bleeder screw with this aluminum version .The aluminum bleeder screw maintains the factory air channel so the bleeder screw does not have to come all the way out to bleed off the air.

The OEM plastic bleeder screw can become damaged from repeated use overtime. A cracked screw can cause air leaks which can lead to a stalling condition, hard start, and other drive ability issues
