Diesel Site HPOP Reservoir Filter Adapter For 1996-2003 Ford 7.3L Powerstroke
Diesel Site High Pressure Oil Pump Reservoir Filter Adapter for 1996-2003 Ford 7.3L Powerstroke
In addition to the filtration benefits the HPRA can be used during the installation of a dual pump setup or supply and return oil for twin turbos to eliminate drilling holes in your factory reservoir. The hole marked "pressure relief return" in the picture below, dumps oil back to the oil pan down the front cover. This is a perfect place to return oil from a twin turbo configuration.
The Powerstroke uses high pressure oil to activate the injectors. At start-up, the high pressure pump (HPOP) draws oil from the reservoir to start the engine, and the low pressure pump is refilling the reservoir with unfiltered oil until there is engine oil lube pressure. This allows a small amount of dirty oil from the oil pan to reach the HPOP and the injectors every time the truck is started. Small fine debris will pass fairly easily, but larger debris can cause pump or injector damage. In mid year 1999 (Engine Serial Number 1039779), Ford integrated a filter screen into the front cover gasket to catch any large debris before entering the HPOP. This new "gasket" with integrated filter CANNOT be retrofitted into an older engine as the front engine cover was machined differently to accommodate it. If you do use this gasket accidentally, you will crack the front cover causing a very expensive repair bill.
ADDITIONAL FILTRATION
- Increases reservoir capacity
- Adds filter screen to 1996 (Engine Serial Number 201681) Through Mid 1999 (Engine Serial Number 1039779) 7.3L Engines
- Factory fuel filter (1999-2003) housing still bolts in place, but minor relocation of the lines are needed.
- Comes complete will all items shown - new gaskets and all hardware for installation.
Capable of Dual HPOP Setup
- 2nd HPOP would be filtered as well
- Ports for 2nd IPR return, 2nd HPOP supply, and 2nd relief valve return
- Bolts into any 94-95 -2003 7.3L engine
- Design eliminates cavitation to the rear HPOP in dual pump applications
SPECIAL NOTE: If you go to your Ford dealer to buy a reservoir gasket for your 1999 model year truck, they will give you the new gasket with filter screen. Someone messed up in the application guide. To get the right one for this model year, you must ask for a 1997 gasket. Our adapter comes with all the gaskets and hardware you'll need.
We developed this adapter to allow the use of the new style filter gasket in the older engines. All gaskets, bolts, and port plugs are included.
CAVITATION: In testing for our PULSE HPOP and building a dual PULSE pump version, we came across something that needed to be addressed. Most dual pumps on the market utilize a 3/8" feed line to the rear pump. Using a stock pump, this is simply not large enough. The rear pump actually pumps at 60% of rated flow. That means your "200%" dual pump is actually pumping 160% of that of stock and the rear pump is slowing tearing itself apart. The noise level from this is deafening when not drowned out by the actual engine noise. I have had some say they can hear a squeal from the pumps but were told it was "normal". Dual stock pumps need a minimum of a 1/2" or #8 line. Our Dual PULSE needed a 3/4" or #12 line!!!! We drilled and tapped a #8 o-ring thread into the adapter for this purpose. Yes, you are reading this correctly. If you install this adapter, and run the larger feed line, your pumps will put out more oil! They will pump what they were supposed to pump. Besides, cavitation will kill a pump of any kind.
