Description Technical Specs
Nicktane fuel filter adapter. Fits 2001-Up GM Duramax Diesel Engines.
  • The Nicktane Cat Fuel Filter adaptor allows you to use the Cat 1R-0750 (shorter more popular) 2 micron large capacity fuel filter on the Dmax engine or the Donaldson P553203 Water separator filter as outlined below. Billet alluminum and anodized black, the Nicktane adaptor comes with the Viton O-rings already installed for immediate installation of the Cat adaptor. We reccomend that you also install one of our MadJack Diesel Performance Fuel Filter Head spacers to make changing filters easier.
    Add a Donaldson 3 micron water seperator filter instead of a Cat filter to retain the water seperator function of your truck with the Nicktane Cat Adapter. If you order a Donaldson P553203 water seperator filter with the water drain then you can also order the Donaldson clear bowl P569758 which installs on the bottom of the filter where the water drain is. This will allow you to see if you have water in your fuel filter. Simply use the drop down menu to add the Donaldson filter and then add the clear bowl. When you receieve your filters unscrew the water drain from the Donaldson filter and screw the clear bowl in its place. Then screw the water drain back into the clear bowl. When you change filters in the future you will remove the clear bowl and install it on your new filter.
    ******If installing this on a 2012 and up LML you must get an LML Fuel Filter Head spacer to make it work.******
