❓ FAQ
It joins the factory HFCM harness to an aftermarket HFCM fuel pump whose connector has been updated. The plug shape and pinout on new pumps differ from the 2003-2007 original, so the jumper carries the circuit across without cutting or soldering the vehicle harness.
Yes. The fitment covers 2003-2007 Ford F250, F350, F450 and F550 Super Duty and 2003-2005 Excursion with the 6.0L Powerstroke V8, which is the engine that uses the HFCM on the passenger-side frame rail.
No. Both ends of the harness are terminated, so it plugs in at the factory harness and at the pump. The original wiring stays untouched, which matters if the pump is ever swapped back.
It replaces 6C3Z-9F759-A and the unpunctuated form 6C3Z9F759A. Both numbers refer to the same HFCM fuel pump wiring harness, so either marking on the original part confirms the match.
The HFCM sits on the passenger-side frame rail, which is why the harness and the pump are reached from under the truck. Relieve fuel system pressure and let the engine cool before unplugging anything.

Description
Product Overview
6C3Z-9F759-A is a jumper wiring harness that connects an aftermarket HFCM fuel pump to the factory harness on 2003-2007 Ford F250, F350, F450 and F550 Super Duty and 2003-2005 Excursion with the 6.0L Powerstroke V8. The harness weighs 69 g (2.43 oz) and measures 9 x 5 x 6 in in its box, and it exists because replacement HFCM pumps now use a different plug shape and pinout from the 2003-2007 original. Fitting it is plug-and-play: no wire is cut, no solder joint is made, and the factory harness is left intact.
