7.3 have whats called the HEUI injection system. it uses high pressure oil to operate your injectors. high pressure oil goes into the injector to operate the plunger that pushes the fuel from the nozzle. as long as you have high pressure oil flowing into your injector you will be pushing in fuel. an HPOP just allows more oil to be pushed into the injector to keep fuel flow going. i honestly wouldnt get one until after you get injectors. heres a website i go to ALOT to get information on my truck, its stacked full of usefull info, it has the explination i just gave you in much more thuro detail, problem is is you have to scroll until you find it
