INSTALLATION INSTRUCTION

  • STEP 1: Park the vehicle on a fla t and level surface. Place a clean rag underneath the fitting to capture any residual fuel that will drain from the lines and filter when disconnected.
  • STEP 2: Locate the under-hood fuel filter assembly on your vehicle. Disconnect the fuel injector return fitting. There are two different styles of fittings that you may encounter in this installation that Ford has utilized. See the guide below on how to remove each of these fittings.
  • STYLE #1 – LIFT TAB: To release, lift the orange tab away from the fitting to expose the locking ring buttons. Once the tab is lifted, squeeze the buttons on both sides of the fitting.
