Fuel pressure at tank

I need to make new fuel lines, and was wondering what the f/p is at the tank, it should be vacuum pressure only correct?? Is the return line under high pressure? The reason I ask is the lines are steel jacketed high pressure lines for some reason. Anyone know why this is? Thanks (as usual you guys undoubtedly will have a good answer)

Thanks for the reply, all I can think is that ford may have used the same lines for the EFI Gas motors as to not have seperate parts, but that almost makes sense- Ford never seems to have a good interchange on parts....

By the way, I love the sig, I am in the Navy right now, and we appreciate all the support from the few that still do! I am going to be getting out in 10 days to pursue my dream of owning an "Automotive Recycling Facility" AKA Junk Yard! All PSD parts will be sold here first ofcourse.

I don't think there should be any pressure or vacuum on the tank itself, the vent you're hunting in another thread should serve to equalize the tank with ambient.
