This spacer kit moves the Duramax fuel filter head 0.5" out from the mounting point, giving you more room and better access for fuel filter changes. As a bonus this kit includes our popular billet aluminum air bleeder screw to replace the cheap plastic factory one that is very prone to breaking/stripping. This kit is a must for anyone running the Cat filter adapters, because the larger Cat filters require the clearance that this offset kit gives you.
