Failure of this pump is a very common issue with the early 6.0L Powerstroke.

We very strongly recommend replacing the 6.0 high pressure oil pump intake screen located in the bottom of the high pressure oil reservoir below the engine oil cooler. In a large majority of cases where the high pressure oil pump has failed, we find that the high pressure oil pump screen is torn. If the screen is not replaced, the high pressure oil pump will fail again in a very short period of time. Some additional time and effort is required to check and replace the screen - but it will save significant time and money in the long run!

Note: If purchasing for a 2004, please do not order until physically verifying which pump you have. Regardless of what some claim, the only positive way to identify which pump you have on a '04 is by serial number or visual identification.

Please note that a $200 core charge will be added to each order (unless your core is sent ahead - see below). This amount is fully refunded upon the return of a rebuildable 6.0 Powerstroke HPOP which has not been disassembled. Please contact us if you have any questions.

Does a 2003 6.0 have standpipes?

Oil System Stand Pipe for the 2003 and early 2004 (Round Style EGR Cooler vintage) Ford 6.0L Diesel. There is one stand pipe per cylinder head.
