Product Details

The FASS DFD-4000 is a fuel filter delete kit designed specifically for GM Duramax diesel engines. This kit allows you to remove the factory fuel filter assembly after installing a FASS Fuel Air Separation System, streamlining your fuel system and eliminating a redundant filtration point.

Key Features:

  • Removes factory fuel filter housing after FASS system installation
  • Eliminates unnecessary restriction in fuel delivery system
  • Simple bolt-on installation with all necessary hardware included
  • Designed specifically for Duramax diesel applications
  • CNC-machined aluminum construction for durability

Important: This delete kit is intended for use only when a FASS Fuel Air Separation System (Platinum or Titanium series) or equivalent aftermarket fuel filtration system is installed. Do not operate your vehicle without proper fuel filtration.

By removing the factory filter assembly, you reduce potential flow restrictions and simplify maintenance, as all fuel filtration is handled by your FASS system. This kit provides a clean, professional appearance in your engine bay while optimizing fuel system performance.

I love this online shop, I will be a repeat customer.

Excellent transaction, I will continue to shop with them.

Quick Shipping and Great Prices!

Will buy from Autoplicity again. I found what I was looking for at the lowest price and shipping was very fast. The website navigation was not as good as some other sites however with persistence I usually found what I was looking for.

GREAT COMPANY

fast service

thanks.

Excellent price and shipping. Easy to order.

Site is nice, wish it had more filtering options, for instance, front brakes only, or rear rotors, etc.

Seems pretty legit. Low prices.

Quick and easy checkout
