Muzzys HFCM Fuel Pump Updated Wire Harness Assembly Fits 2003-2007 F-250 F-350 Ford Super Duty 6.0L Powerstroke 6C3Z-9F759-A Horizontal Fuel Conditioning Module Current Style

Item worked as it should Just plug in and go but I would recommend beefing up the wiring inside the loom itself there’s no wrapping to the wires for support other than that seems like it will work just fine

I needed this to replace the HFCM (whole fuel pump assembly) on an 03 F250 6.0 Powerstroke. The original pump assembly has 3 plugs and I realized I needed an new harness when the new pump arrived. I got this one because it was priced right and would arrive in one day, thanks to Prime shipping. I connected the plugs and the truck fired up right away. Just one thing to note- the Ford Motorcraft assembly has a gray and a black plug. So does this wiring harness. However, the gray harness connection goes on the black pump plug and the black harness connection goes on the gray plug on the pump assembly. That seemed totally backward to me, but that's how it goes. The truck won't start if you wire it black to black and gray to gray (that's how I first connected it by mistake). This definitely did the job and the truck runs great now.

Bought my updated fuel filter housing and this plugged in to my harness and the housing correctly without problem. The two connections that go to the housing you can't mess up because each plastic housing is tailored for its correct connection. Do not concern yourself with the colors. For mine black went to pump Grey goes to fuel water separator. Plug and play and works with zero fault codes on my OBII reader. Cheers from a back yard/ weekend warrior mechanic.

Works great the oem one just stopped passing power

The quality is poor, the secondary plugs are not wired correctly. The grey plug is for the pump, not the sensor, and the black plug is for the sensor. The one I received was wired backwards so I had to switch it so the incorrect plug colors are on the connectors. The main harness connector is not water tight at the wire penetration side. The unused holes are not blocked off which will allow water to enter what is supposed to be a watertight connector. The secondary connectors do not fit well over the existing plugs. They are fair at best but not as good as the factory connector. I should have just purchased the factory OEM connector harness.

This was perfect for the newer style fuel pump assembly on my 05 excursion 6.0

Great product so far. Stopped by the local ford dealer and the OEM part I needed had been on back order since November. This got me out of a pinch.

Need to replace my wire harness along with the fuel pump for an '06 F-450. Harness fit the pump perfectly. It's been months and I have had no issues.

Thank you good service and good price
