We have put together this "Emergency Roadside Repair kit" that every owner of a 99-03 7.3L should keep in their toolbox. Eventually, the 7.3 will develop a fuel or oil leak.

Rather than having to run around town, hoping the dealer has the parts you need or be stranded on the side of the road in a desolate area that the tow-truck driver can not even find you, be prepared and have the parts on hand. Don't worry about the o-rings drying out or cracking, The shelf-life of DuPont Viton is forever, they won't go bad from air, heat, sunshine or time.

* Choices of Types of Drain Valve o-rings

  • Black Viton Type A
  • Blue MilSpec M25988/2 Fluorosilicone.

Note on the Fluorosilicone Option: 

Fuel Drain Valve o-rings: A set of 2 High Quality Fluorosilicone MilSpec M25988/2 (FVMQ) O-rings for the Fuel in Water drain valve and 1 Viton O-ring for the valve stem. For the drain valves on both the 1994.5-1997 trucks and vans along with the 1999-2003 trucks and vans.

Black Viton Type A The black Viton o-rings are polymerized from two monomers, vinylidene fluoride and hexafluoropropylene (Viton type A). The low temp flexibility of Viton(A) is -2deg F but will continue to perform well in our type of service at a much lower temperature (-20 F)


Blue Fluorosilicone The Blue Fluorosilicone elastomer is a Military Specification material that has a much wider temperature range than Viton (A) or Viton (B) and is widely used where fuel contains corrosive agents that are found in ULSD. Bio and veggie fuels. They will stay flexible in arctic conditions down to -70º F and can withstand temperatures in excess of 400 F.

Parker From Parker Hannifin :

"In the automotive market, fluorosilicones are the seal material of choice for handling gasoline, E85, diesel fuel, biodiesel and ULSD at extremely low temperatures."

O-ring GTP-38 Main compressor housing o-ring - Genuine Garrett part# 403069-0199. O-ring for the seal between the main compressor housing and compressor back plate. If your housing o-ring is damaged or broken, boost will be severely compromised leading to higher EGTs and low performance.

Order the Compressor Housing o-ring by using the check box at the top of the page.

Serviceable Plug:

serviceable plug
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 form high quality 303 stainless steel that when added to this kit is discounted from the regular price for only $26.38.

Bosch has been manufacturing their new pumps with a "long threaded plug" for the last 2 1/2 to 3 years, thereby acknowledging the engineering defect that they have had on these pumps.
This plug can successfully repair a HPOP "non-serviceable" plug that has completely stripped out the factory threads.

Add this kit by using the check box at the top of the page.


HPOP Mounting Gasket:
hpop gasket

When replacing the "non-serviceable" plug the HPOP must be removed from the engine. The HPOP to front engine cover gasket is not considered to be reuseable and it's highly recommended to replace it.

Order a new Genuine Ford/Navistar gasket by using the check box at the top of the page.

HPOP Quick Release Tool
tool The HPOP 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 using the check box at the top of the page.
