sounds like your 'new' tank lost the vent nipple on the filler neck?
the vapour tank has 3 nipples, one at top and 2 at bottom.
top: this one has the little vent valve and goes to that hard line running along the cylinder head - that looks correct on your set up.
middle: this goes to the filler neck (on yours it goes to the tank)
bottom: goes back to tank (on yours capped off)
see post #3 here for original set up:
diagram is useful too (not spider, OK, but same thing!):
