dual function resevoir

i have a 1986 f150 302 fuel injected. im having trouble putting back together my dual function resevior(6 port). i took it apart to try to clean it and i cant figure out how to get the valves on the bottom off. i think its the 20 psi divereter valve and 5psi anti siphon valve off. i took of the rubber o ring of them and they went back up inside and cant figure out how to put them back on. thanks

Why in the world they call the fuel tank switching valve a "reservoir" I'll never know, but that's what they call it and that's what he is messing with.

With air in the fuel lines it may run rough for a little bit, but the air will be purged pretty quickly through the return lines.
