Never done this on the 7.3L I have done it on the GM 6.2L and 6.5L a lot of times. But the pumps are different between the 7.3L and the 6.2L and 6.5L. I will say this you don't want to turn it up to much or the engine might run away.

i kno i looked at a 6.5l at my tech school and the pumps are pretty similar i jus need to kno if the nut should be tight or not
