Delivery Valve Seal
Anyone ever have to replace the o-ring/seal underneath the fuel delivery valve of an IP?

All it takes is a 30-point socket.

I did about a month ago, it was pretty straight forward. Remember to replace the copper washers (valve spring seats) at the same time.

where did you get the socket and washers? Is this also called the seal ring? Why did you get in to this? Was it leaking?

I may be way off
but this is what I just bought and used to replace the o-rings. It worked really well, and seems to be built ok. I'm sure there are better ones on the web, but most are still as pricey.

I did mine the weekend after Thanksgiving. Pretty straightforward. Got my O-rings and copper washers from Rusty. Borrowed socket from a friend. Did each injector one at a time starting on #6 - 5 - 4-.... You must keep in mind the torque spec when tightening.
Goodluck

I got the washers from Seattle Injector Service; just phoned them and gave them the IP number (the most useful number for him was the Bosch number, which starts with 0400). They mailed me the washers and seals. You can always get it from Rusty through the link at the top of the page. I had to replace mine because a couple of them were leaking.

Ditto what everyone else has said -- mine were leaking badly on the '87. Got my parts from the dealer, socket from same ebay source.
Fairly easy repair. Read up here first though. If you take too many parts outta there, you'll fubar your pump!

El Paso Tools is a good e-bayer. I've used him. I also have the socket that I used on my 606 engine. It's available for a small rental fee/deposit if you find out it will fit yours.

Part 7f is the copper crush washer and 7h is the o-ring seal.
When the o-ring seal fails, diesel comes out the top of the IP. The spring wears itself a 'home' position on the copper washer; if you remove the spring you need a new crush washer for the spring to seat properly.

Replaced the delivery valve seal and copper o-ring. Got the spline socket from the dealer. Seal and o-ring from the local diesel injection specialist. Just gave them the Bosch Inj Pmp SN#. They had it all in stock for $2.58 a set.
Turned out to be a simple job. While I was at it, I wanted to replace the primer pump with the new Bosch pump. But I had a tough time unscrewing the fitting where the primary fuel filter goes in to. I just could not budge the 22mm hex fitting. Its a tight spot down there and the stubby combo wrench could not do it. Have to remove this fitting since its in the way of removing the old pump. But, since the old pump still works ok, I backed off from doing it. Can't believe how easy the car starts now. It was 25 deg this morning and it started at first crank. I believe its due to no more leak in the fuel and injection system.
