Need to replace leaky fuel lines (rubbing against tranny over 6 years ) — using ‘94 lines to the 5.8 in my ‘52. Junkyard only had a ‘93, but in addition to slightly different material it is missing what looks to be a regulator inline in the ‘94 (blue hose, top)?
So do I need to track down a ‘94 (or ‘95 since that was the donor)?
TIA
Can't recall if there has ever been a definitive ID posted of that device, but I believe that it is a pressure "damper" to reduce pressure fluctuations.
But for some reason it's on some, but not others.
I'd use what you have & if the later style shows up, grab em'.
ISSUE: A fuel system "knocking" noise may be heard. The noise is caused by fuel injector pulsations that are transmitted through the fuel lines.
ACTION: Install a new front fuel line assembly with a pulse damper. Refer to the following procedure for service details.
SERVICE PROCEDURE
1. Relieve the fuel system pressure. Refer to the 1992 F-150-350, Bronco Service Manual, Page 10-01A-26, for fuel system pressure relief procedure.
2. Remove the existing front frame to engine fuel line assembly. Refer to Figures 1 and 3 for fuel line disconnecting procedures on each end.
3. If any material was installed to isolate the "knocking" noise previously, remove it.
4. Install the new front fuel line assembly (F3TZ-9J338-G or F3TZ-9J338-H) with the pulse damper. Refer to Figures 2 and 3 for installation procedure.
5. Check the system to be sure there are no leaks.
