I'm in the middle of an engine replacement for my '97 GT (4.6L)

It's being replaced by an '02 GT model - complete engine swap.

I know i have to use my fuel rails - BUT - how will I pressurize the fuel system or do I need to pressurize it?

If so, to what amount of pressure? I'm seeing anywhere from 30-40psi in the forums as starting points and then adjusting from there depending on how you want your car to run (how rich of a mix).

I'm still searching the forums but could use a little guidance here as we're now finishing pulling my old engine and will want to begin the installation of the new one this afternoon.l

any help is much appreciated :bounce2:

When you get it all buttoned up, just turn the key on without starting it, and you'll hear the fuel pump run for a few seconds. That's what it's doing it building pressure in the lines. Try to crank it over a couple times, if it doesn't start, turn the key off for a few seconds, turn it on, let it prime again, and you should be good to go.

I've never had much of a problem getting the pressure back up into the rails just by doing that.
