THe 5.9l have the regulator built in the pump, only the 3.9 and 5.2l have an external regulator between the throttle body and the distr.
After all.....you were right !!
May be we could use that regulator with a universal pump ?

Didn't know any had an external reg. I gave up on that after trying to use a mustang one, and just bought the aeromotive regulator. A bit more expensive, but I figured it was worth it vs trying to hack something together.
My only concern with the 3.9 and 5.2 regulator would be flow. Why would they make it different would be my next question. They don't do it for the fun of it. So they must have needed the in tank reg and pump for a reason on the 5.9.
