ISSUE:
Some 2015-2016 Edge and 2016 MKX vehicles equipped with a 2.7L EcoBoost engine and built on 10/29/2015 and through 4/1/2016 may exhibit a knocking/tapping noise that can be heard in the fuel feed tube that attaches to the high pressure fuel pump on the engine. This may be due to a loose check valve located in the fuel feed tube.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
- Check the vehicle build date. Was the vehicle built on 10/29/2015 and through 4/1/2016?
- Yes – proceed to Step 2.
- No – this article does not apply. Refer to Workshop Manual (WSM), Section 100-04.
- Inspect the oetiker clamp on the fuel pump feed tube. Can the clamp be rotated by hand on the fuel feed tube? (Figure 1A)
Figure 1 - Release the fuel system pressure. Refer to WSM, Section 310-00.
- Disconnect the battery ground cable. Refer to WSM, Section 414-01.
- If equipped, remove the two retainers and remove the engine appearance cover. Torque: 5 Nm (44 lb-in)
- Remove the right hand air cleaner outlet pipe. Refer to WSM, Section 303-12.
- Disconnect the fuel feed tube and vapor tube quick release couplings. Refer to WSM, Section 310-00. (Figure 1B)
- If equipped, remove the retainers and the floor pan underbody shields. (Figure 2)
Figure 2
- Remove the retainers and the front crossmember brace. Torque: 45 Nm (33 lb-ft). (Figure 3)
Figure 3 - Disconnect the fuel feed tube-to-fuel tank and vapor tube quick release couplings. Refer to WSM, Section 310-00. (Figure 4A)
Figure 4 - Remove and discard the fuel feed tube, vapor tube and eight mounting brackets. (Figures 1C, 4B, 5A and 5B)
Figure 5- It is not necessary to remove the two brake lines.
- On the new fuel/brake line bundle, remove and discard the two brake lines from the fuel/brake line bundle.
- Install the new fuel feed tube, vapor tube, and eight mounting brackets on the vehicle.
- To install, reverse the removal procedure.
