Yes, this is the discharge tube. To remove it, you'll need a "quick-release" type tool to insert into where the black plastic sleeve is, compress it and pull the tube outward. Once removed, apply shop air into the branch tube using a rubber tipped air nozzle. The purpose of using a rubber tipped air nozzle would be to ensure that air doesn't leak out between the nozzle and the opening into the branch tube. The purpose of applying air pressure into the opening, is to pressurize THE REST OF THE HIGH PRESSURE OIL SYSTEM. Does this make sense now? So now, if you hear no air exiting with air applied, it means you don't have an issue with any other part of the system, other than what you've already removed.

By the way, pay very close attention to what the discharge tube looks like, around the curved part of the tube. Does it look like it has contacted the under side of the high pressure oil pump cover? If so, you may want to replace the cover and tube as well.

Thanks a bunch. I don't have the correct tool, so I reinstalled the HPOP and put air into the top. I'll post a video soon.

It did seem like I heard a faint squishing sound coming from the passenger side injector area. Should I pull the valve cover off to better listen to see if any of the injectors are leaking oil?

Pull the passenger side valve cover off and repeat the test to pinpoint the source of the leak. I'll bet either an injector has blown its top, or the standpipe to the rail has popped loose.

Sounds like it is #1 injector is leaking oil (which I replaced in the spring)

Where can I get replacement O rings. I suppose the people I bought the injector from should hook me up since the injector is already bad (injector warehouse)

I'll now take a break eat and relax before pulling the oil rail so I don't drop a bolt into my engine (not that I have ever done that before)

Ok there looks like there is a gasket about 1/8 to 1/4 " into the injector in a groove that runs around the inside that is bad.

So the question is can this be replaced/fixed?

That set of seals doesn't have the injector "D" ring in it. That's just for injector replacement. You need set AP0002 listed here: Industrial Diesel Engine Replacement Parts Dealer, Aftermarket Rebuild & Overhaul Kit Systems Supplier

Can I reuse the gasket under the hpop cover?
Would NAPA have a good sealant for the corners or do I need to get the motorcraft stuff?

****For anyone removing the HPOP you don't have to drain the oil. I thought I did and managed to spill half of it. Adding another $100 to the repair!

The high pressure oil pump cover gasket can be re-used as long as it wasn't damaged during removal. However, does your truck already have the updated cover with the machined groove on the underside? How about the condition of the discharge tube? Is there any evidence of contact with the under side of the cover. Because if so, now would be the time to replace the cover and tube.

I didn't see any evidence of contact. I just found a picture you posted of the old/new cover and will recheck it. While I am in there I will replace the o-ring even though it looks good.

There is a plastic sleeve stuck inside the hole the IPR goes into. I assume that is from the IPR. Any suggestions on how to get it out?

Should have all my parts FED EX Friday. Then just have to put it all back together :-)
