1984 2.2 dsl engine fuel leak on IP????

I have a 1984 2.2 dsl engine that is leaking fuel from a part I believe is called the fuel delivery valve. The injector lines connect to this part located on top of the IP. The line connection is not leaking! The leak is coming from where this component screws into the IP. Is there an o ring that goes bad over time and is this a common problem? You can see where I'm talking about if you go to this link and view the IP pic on the 3rd page down. The leak is coming from the base of serated component in the top left of the pic. I have taken the hold down off to verify. Also what tool or socket is used to remove this? Any part names and numbers I'll need? Thanks

Starting my Diesel conversion 2.2 into 87 190E body

Parrot of Doom did an excellent writeup on taking care of the delivery valves. Hopes this helps

Special socket fits the delivery valve, about $40 if I remember correctly. Use caution with the metal fuel lines as they are prone to leaking anyway and have to be replaced if a leak starts. 4 o-rings and 4 copper washers and you'll be leak free.

Make sure you have a good hex tool for those intake bolts ,stripping one is not a good thing.Your fuel lines will most likely need a new set of line holders ,these are very crucial to the lines not leaking ,if no supports are in place ,leaks will soon be following with no mercy.

I was able to change the O-Rings and crush washers below the fuel distribution valves in the IP, now I need to get the air out of the lines from IP to injectors. Need help and suggestions. Thanks

Loosen the Fuel Injection Hard Line Nuts at the Injectors and that will let out any Air trapped inside of the Fuel Injection Hards Lines.

Don't crank too long all at one time but you need to crank enough that Fuel comes out from under the Fuel Injection Line Nuts at the Injectors and then tighten the Fuel Injection Line Nuts at the Injectors and try to start.

If that does not work loosen them again and repeat the above.

Above is fine, and the 60x fuel injection systems are self bleeding. Crank for 30 seconds or so, wait a minute, and crank again. Shouldn't take long.

When I replaced mine, I didn't bleed at all.

WD-40 sprayed into the intake was the ticket. You may have to keep spraying it a few seconds after the motor hits until the fuel system pumps out all the air.

Good luck!

Hey, thank you all for the suggestions, I was able to crack lines at the injectors. However only got fuel to #4 but misted some dsl fuel into the intake and got it putting. Things finally got better as the air cleared out. Next and last thing to do is change the cam followers (lifters), if that goes as well as this did, I'll be thrilled. This job wasn't bad as I did it without removing the intake or lines. Having others to offer up help is a great benefit.
