There is boatload more to come. After engine oil has been cooled off and filtered, some of it is sent to the oil reservoir beneath the oil cooler located within the block and at the front of the lifter valley. The oil present in the reservoir feeds into the high-pressure oil pump HPOP located at the rear of the valley the HPOP is driven via the rear gear train.
At a minimum, psi is required to start the 6. Luckily, during most HPOP failures, metal debris is not passed on to the oil rails and ultimately the injectors. Within the oil cooler reservoir and cast into the block is a provision to accept an HPOP filter also referred to as the inlet strainer. This filter is responsible for keeping debris from being passed directly into the HPOP.
Unfortunately, its cloth mesh screen is notorious for tearing or becoming brittle and breaking down over time. When this happens, there is nothing to stop contaminants from reaching the HPOP—and sometimes the HPOP even ingests fragments of the broken down screen. It goes without saying that the HPOP filter is a fragile piece.
To rule out the issues associated with the HPOP filter, install the updated version from Ford, which carries part number 3C3Z-6CAB and features a much more durable stainless steel mesh screen rather than a cloth one. This can be done any time the oil cooler is replaced if you recall from Part 1, oil cooler failure is the most common problem on all 6. Speaking of both oil cooler replacement and the new HPOP filter, always make sure no dirt or other debris gets into the oil reservoir.
Keep it as clean as possible. Anything that gets in here has the potential to go straight into the HPOP. There are a plethora of ways the 6. A failed oil cooler O-ring will get caught in the HPOP filter, inevitably break down so as to cover the screen, restrict oil flow to the HPOP and potentially eventually kill it. The best way to avoid this type of failure is to always install an OEM Ford oil cooler and not a cheap aftermarket knock-off.
You never want to pay for or perform an oil cooler job twice. As a long-time builder of high-pressure oil pumps for the 7. USD Customize Your Item.

A minimum of psi is needed to fire the injectors, but if your pump has failed then your truck will stall or fail to start completely. Each one is a drop-in replacement for your factory unit and requires no additional modification to fit so you can minimize down time and get your truck back on the road where it belongs.
