#1 vacuum line 1990 GL-1500

Post by n5926g » Mon Sep 07, 2015 7:19 am

Morning guy,s.
After a lot of confusion on the vacuum line connections,I am down to one line that
I cant figure out where it terminates....This is a #1 line that comes off the vertical port of
#4 intake.I do have the line schematic in my FSM,and it "appears" to connect to the "#1 pink"
line eventually going to a "T" and then to the airbox,and hot air door on the intake box inlet...can anyone confirm this?

Vacuum line routing did change significantly over the years.

Sounds about right for an early vintage.
