vacume lines keep cracking.I keep replacing them with oem plastic lines not knowing the lines themselfs are the problem
while changig spark plugs, i had to move plastic vacuum line, and the plastic vacuum line where no longer flexable, they where very rigid and brittle, as a result they broke very easily.
