❓ FAQ
It moves the filter head 1/2 in (12.7 mm) further outboard, away from the intake. That is enough to get a socket square on the cap, or to turn it by hand, instead of working around the manifold.
Yes. Two bolts have 30 mm of thread for the 2001-2010 head and two have 45 mm for 2011 and newer, so the same box covers both castings. Fit the pair that matches your model year.
The factory screw is plastic and its threads strip after a few bleed cycles, which is when air starts getting into the fuel system. The aluminium screw in this kit keeps its hex and thread through repeated use.
No. The pack is the spacer plate, one aluminium bleeder screw and four bolts. The seals on the filter head stay with the housing, and the element carries its own O-ring.
No. The spacer and the aluminium screw are accessories added to the factory head, so no OEM part number is published for them. The only thing it replaces is the original plastic bleeder screw.

Description
Product Overview
MDP-AD04-BU is a billet aluminium spacer kit for the Duramax 6.6L fuel filter head, and it does two things at once: it moves the housing 1/2 in (12.7 mm) outboard so the cap can be turned without fighting the firewall, and it swaps the factory plastic bleeder screw for an aluminium one that does not strip. The pack carries the plate, the screw and four bolts, two at 30 mm thread for 2001-2010 trucks and two at 45 mm for 2011 and newer, so one box covers both bolt patterns.
