❓ FAQ

The 2001 to 2013 GM Duramax 6.6L filter head, which covers Buick, Cadillac, Chevrolet, GMC, Hummer, Saturn and Pontiac models that use the same hand primer.
Six seals: two nitrile plunger U-cups and four Viton O-rings, plus the aluminium bleeder screw.
No. The primer is rebuilt in place; the filter head, the fuel lines and the mounting stay where they are. Only the primer is opened up.
Yes, soak them in clean diesel first. A dry nitrile cup can roll or tear as the plunger goes back in, and a rolled cup leaks air exactly like a worn one.

Description
Product Overview
SL6AD4-BU is the seal rebuild kit for the hand primer on the 2001-2013 GM Duramax 6.6L fuel filter head, supplied with an aluminium bleeder screw in blue anodised. The pack holds two nitrile plunger U-cups, four Viton O-rings and the screw, so a primer that is drawing air is repaired by replacing these parts instead of the whole filter housing. The screw measures 0.38 in (9.7 mm) across, which is the diameter the filter head takes.
