I am glad that someone is finally able to produce factual data from Bosch.

When can we expect to see the letter or press release from Bosch regarding testing and limitation standards of the inlet fuel supply for the VP44 used in Dodge Ram series trucks?

It will be refreshing to see the actual stance of the company and not some half hearted repeated out of context, friend's, brother's, 2nd cousin's, high school guidance counselor's local burger flipping authority has to say about it.

I love good info! Up to this point, I don't think many of us has gotten to see an actual company document regarding this hotly debated topic. I know I sure haven't. And I can't wait!

If you need my e-mail, drop me a PM and I will happy to post it up for you.

THe vp44 only likes 4 psi on cranking. Says so in the manuel. I actually called Cummins a long time ago and asked why. They said they didn't know why, Just that it doesn't like a lot of pressure when cranking. So if it still won't start, I would look for some other reason. Possibly drain back and introduction of air some where.
