Billet aluminum MAF bung for 2011-2016 LML Duramax. The bottom side has a 4.5″ radius machined to fit any 4″ or 5″ tube and includes 2 stainless socket head mounting screws for the MAF sensor.
This sump is designed to help ease the install of 2 lift pumps. With its 2 suction ports, installing 2 lift pumps is a breeze! It is based on our proven clamp in design that we use on our integrated return sump. We include 1/2″ push-lok fittings and a hole saw.
