Billet aluminum MAF bung for 2001-2007 LB7, LLY & LBZ 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.
When installing a bottom sump with your AirDog or Fass Pump most trucks end up with an open fuel supply and or return line. Our 1/2″, 3/8″ or 5/16″ aluminum plug will cap off these lines with ease, to keep fuel from seeping out of them and dirt from getting into your fuel tank. You no longer have to mess around trying to figure out how you’re going to plug off these lines. Simply clip our Quick-Connect plug into that open factory fuel line and you’re ready to hit the pavement!
