4.9 efi vacuum lines and bogged down when throttle is pressed

I am currently experiencing vacuum line breaks and not understand ing how they run. Also the truck runs really rough when it does start and only runs for a few short seconds. But when throttle is pressed acts like no fuel. Take your foot off the throttle and it idles back to where it's supposed to then dies. Please help thanks. You can text me directly at 4056968784 thanks forum for your time and effort.

You can use this link as a reference. Replace all the plastic stuff with rubber.
