Vince, you still working on that thing?

Vince, ya gotta admit. I know you shake your head at us un-trained (mostly) wise guys that maybe take for granted what you guys do at times, but, there are a lot of good ideas being thrown at you to try to help.

And really, any idea is a good one.

Seems to be working fine. The owner wanted us to drive it for a couple of days to verify the repair. It started ok this morning.

I believe it was a combination of two things leading to the unusual nature of the concern. The viton coated washers on the fittings of the high pressure pump (one is the feed, one is the return),contributed to the bleeding down of the fuel when shut off. The two solenoids on the pump were (in my estimation) sticking slightly (both tested ok), contributing to the aeration of the fuel while running.

Good to know. I had a feeling that maybe those seals were an issue. I suspect that more will fail in the future. Maybe not.

There is a tool used to bleed the high pressure side. It has a clear hose. When bleeding, previously, you could see "champagne" bubbles in the hose while running. The FSE said it was normal-"Turbulence". Now, there are no bubbles, its completely clear. Is that an indicator of a future failure of a pump............I dont know, its something to think about however.

vince we have not has a single viton washer fail yet. also all the bleeding of 6.4 have no bubbles when fully bled. we do see a lot of sticking vcv and pcv valves.
also got told that allowable water contant is .05% in mix after that cp for sure. sadly cant get it in writing so from anyone. but we did get ford to send a sample and based on the 1% water in the sample container they declined and job went cp.

If anything that should tell all of us to make sure we drain the fuel/water separator monthly and change those filters!
