Need fuel tank help

[jorchy]

I am replacing the tank assembley on a 90 FI festiva. There are some lines that go next to the filler tube and I broke one off. There is the filler tube then vent tube. Then a lower line that goes to the front of the car and up toward bthe side. Then there are 2 more toward the end of the tank The second one from the rear side is the one I broke. Do I need to repair tubes or can I just block them off. Are they just for emmisions. Any help would be greatly appreciated

i did the same thing. buy a new tank some kind of fuel vapor vent, air needs to replace the fuel as it's used or the fuel won't come out. it would probably be cheaper to buy a new one than to have the old one repaired. safer too. gas doesn't play well with others. rockauto.com has it listed for $177 new or ya can try your luck at the junk yard.
