The 94 is injected, so you have a different intake setup. The 88 is carbed. The small hoses are vacuum lines and they should be connected. They are problematic at best. You need a Chiltons manual or similar to assist you. Your best choice is to abandon that carb altogether and buy a replacement from JC Whitney or Quadratech. The factory carb is a Rochester and were always junk. Try a new Weber or somebody else'.s.
