Heater hose crossover hose question

[Jim S]

My 87 has small hose that runs from a tee in the heater hose on the driver's side of the engine.  It  connects to a nipple in the intake manifold under the distributer. I installed an new distributer with the internal coil and this connection interferes with the vacuum advance.  Is this hose necessary?  I would like to remove it if I can, but I don't know it's purpose.  Thanks.

Move your wires around the cap in either direction to make clearance from the vac pot.  Move the distributer base in the same direction you move the wires.  Then set the timing again.  The base does not really care where it is positioned, make it have clearance  and adjust timing accordingly

Between the heater hoses coming out the firewall, the intake manifold and the cruise control stuff, there's few areas to move it.
