Moderates the severe pulses created in the injection pump. Also it is thought to reduce noise.




Looks like the vast majority of these cars run well if it is not present. Only one case that I am aware of that it made a difference in running.


I suspect it was in combination with perhaps another issue present but no attempt was made to locate it. This also may have not been the case.




Anyways putting the cigar hose back in did cure the issue. The car ran differently depending on the level of fuel in the tank without the hose. Remember this was the only case I ever remember.
