tape dont work well.
if you have advance auto near by, go there, look for a two pack of white small T's they cost 2 bucks. buy a foot of vac line, thats like a buck a foot.
put 1 1/2 inch long vac line on all 3 sides of the T, then push one side to the lim, and the two plastic lines into the other two lines.
do the same for the FPR too. you got 2 new T's, use em.
also the injector o rings, if you didnt lube the o rings before installing them one could have rolled out of place or broke on you. spray it down with carb cleaner. if the idle jumps you found the leak area.
