Understanding STC Components


Before removing the HPOP, it is necessary to remove the fuel canister on the 99-03 7.3L. The 4 hard lines will require new sealing sleeves as these are not reusable and will leak if attempted to be reused.

We recommend purchasing the 7-003 Fuel bowl reseal kit that contains the 4 new sleeves for these fittings.

It is easy to lose the Bypass Pressure Relief stainless ball seat when disassembling the valve. Always try to keep the valve pointing up when replacing the oring but if it gets lost, we have replacements.

HPOP Quick Release Tool

The High Pressure Oil Pump hoses on the 1999-2003 Ford 7.3 diesels have a quick release style of hose end that requires a special tool to disconnect the hoses from the pump and the head fittings. Some have used screwdrivers to release the connection but it is easy to damage the hose without the proper tool.

You can easily add this tool to your order along with the HPOP kit by adding it to your cart using the check box above.

LEAKING "non-serviceable plug"? Now it is SERVICEABLE!

If your "non-serviceable" plug at the bottom of the HPOP is leaking, it is probably due to the short threaded plug stripping the threads from the aluminum HPOP body. We now offer a new 'long threaded" plug made from high quality 303 stainless steel . This plug can sucessfully repair a HPOP "non-serviceable" plug that has completely stripped out the factory threads.

Add this kit to your order by adding it to your cart using the check box above.

HPOP Engine Mounting Gasket

The HPOP must be removed to replace the "non-serviceable" plug and the HPOP to front engine cover is not reuseable.
