4wd vacuum question

1989:4.2L:nuttered:weber 32/36

After nuttering my jeep, installing a weber carb and taking off the 3 vacuum solenoids I was left with a vacuum line for the 4wd that T's twice. I'm not sure why it is, maybe it was hooked into the 3 vacuum solenoids that I got rid of when I pulled the computer from the loop. In any case, can I get rid of the T's in the line to make it one straight vacuum line and hook into manifold? If not, maybe someone could help me with where the 4wd vacuum line(s) go.

You'll see a red line with a checkvalve at the end. That is the vacuum source for the 4wd. You can clean up whatever leftovers there are as long as you have that is hooked up to manifold vacuum.

If it is temperamental, it is probably easier in the long run to replace all the vacuum lines you have left instead of trying to find leaks and repair individual sections.
