Guess you missed my first post on your problem:
White smoke is normally an under fuel indicator....
good luck

Pumps are matched to injectors, and engine. You should stick with all 6.2 or
6.5 parts as they are meant to be together. A friend of mine with a fuel
shop once told me how much he loves junkyards, as they will sell "cheap
people" a pump or injectors. That doesn't work most of the time, and the
people come back to him and then have to spend even more so he can convert
what they bought (having lost the correct core at the junk yard) or sell
them at core and then build it for their application.
