Question for Old Magnet? I'm getting ready to fix the fuel leaking into the injector pump housing on my 9U D6 Going to replace the 8B4967 seal. Are there any other seals or gaskets that I'm going to need to complete the repair? 
Many Thanks!

Just the one o-ring seal 8B4967 used on the late pump housings.
You will also need the 4F5148 housing gasket and while your in there replace the 1H5959 camshaft seal.

What vent line are you seeing leakage from? If coming from transfer pump you have a seal problem with the pump. If coming from the injection pump housing
that's internal leakage past the injection pumps. If your getting fuel in the main engine sump that's an 8B4967 o-ring problem.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
