Fuel pressure regulator
Going to replace the fuel regulator on my 1995 f150 4.9. When I look at the the different fuel regulators the all look like mine but some are 41 psi and some are 55 psi how do I know which one I need?

Update on fuel pressure regulator
The part store shows their identical in appearance and shows both are for 4.9 but when I read the specs one is higher than the other. I checked my old one with a pressure gauge hooked to a vacuum pump it stays steady on 15 psi for several minutes doesn’t move at all. So I walk away come back 10 minutes or so and it’s zero. Is this the right way to see if it’s good? You have to take the plentum off to change it and everyone knows what a pain in the butt that is after motor is in the truck so I want to be sure but those things are cheap for that year.
