❓ FAQ

Description
Product Overview
SL6AD4-SI is the seal rebuild kit for the primer on the 2001-2013 GM Duramax 6.6L fuel filter head, supplied with an aluminium bleeder screw. The pack holds two nitrile plunger U-cups and four Viton O-rings, which are the seals the primer actually uses, so a leaking primer is fixed by replacing nine small parts instead of the whole housing. The bleeder screw is machined from 6061-T6 billet and silver anodised, replacing the plastic screw whose threads strip.
