Most Popular Questions

Is this update needed for an 03 engine?
View Staff Answer 
The Ford STC HPOP Fitting Update Kit 4C3Z-9B246-F will only work with the 2004.5+ 6.0L's built after 9/22/03.
I have a 04 F350 that I bought new in May 2004. I don't know the actual build date, can it be determined without the truck?
View Staff Answer 

Call your local Ford Dealer with your VIN# to check the OEM # on your HPOP. If they say you have the 5C3Z-9A543-ARM pump, then this update kit is correct for your application. If they say you have the 3C3Z-9A543-AARM pump, then you have an early 03-04 application and this kit will not work with your truck.

On the 04 I found out I have a 4C3Z pump, the tech didn't know if it needed updating. Do I need an update?
View Staff Answer 

There are no updates available for the 2003-2004 Ford 6.0L's with High Pressure Oil Pump (HPOP) 3C3Z-9A543-AARM. This kit is specifically for the 04.5-07 Ford 6.0L's with High Pressure Oil Pump (HPOP) 5C3Z-9A543-ARM.

The best way to determine if this Fitting Update Kit will work with your application is check you build date & ICP sensor location. Trucks built after September 30, 2003 and/or ICP sensor is located on the passenger side valve cover (above the glow plug control module) would use this kit.

The OEM# that Ford provided me for my HPOP was 4C3Z-9A543-ARM. Will this kit work?
View Staff Answer 

I believe you are referring to the Ford 4C3Z-9A543-(AARM). This would make the truck a late production 2004. This pump is different from the 05-07 pump and would not use the STC HPOP Fitting Update Kit 4C3Z-9B246-F.
