Yes. And the fuel bowls are still full - at least the secondary bowl is. Is that enough to cause the stumble? Does it need 6.5 the whole time? I don't want to go thru and replace the entire fuel system (again) and have it still have the problem.
Is fuel pressure dropping from 6.5 to 4 enough to cause a problem if the bowl is still full?
