Fuel pump question for 1997 7.3

Hey! I just converted a 97 f-350 to run on veg! I have a raw power pump pushing the wvo through 2 heated filters at 30 psi then it goes through a pressure regulator that reduces the pressure to about 10 psi then that runs through a fphe then to the stock mechanical pump... It is running great but I'm wondering if pushing 10 psi of wvo to the stock pump (which pulls at 4 psi I beleive) is gonna damage the stock pump? Or if the regulator will make the raw power pump work too hard?... I am pretty new to all this...

just get rid of the mechanical fuel pump and make both the diesel and veggie side use electric fuel pumps. My question is you must have a return somewhere back to the wvo tank for all of this pressure to go back to right?
