The Merchant Automotive 10368 Fuel Filter Head Spacer for your 2011-2016 GM 6.6L Duramax helps with the tight fit to squeeze a filter wrench around the fuel filter with the newer longer filters. GM designed a step in the bottom of the can to help with the problem, but its still very tight, especially with the wires routed close to it. A 3/8" thick aluminum spacer was developed to move the filter head away from the valve cover. 

This provides enough room to allow a fuel filter wrench to slip in for an easier filter removal and re-installation  Install is very easy. Simply take out the two bolts that hold the filter head to the support bracket and install spacer and longer bolts. No fuel lines or wires need to be moved or extended. 


  • No Modifications Needed
  • Simple Bolt-On Installation 
  • Provides More Room For Filter Wrench & Filter Removal
