I have a vacuum line that is broken, it goes to the egr vacuum sensor. I
spliced a piece of tubing to reconnect it. I would like to replace the
line. It is the red line. It goes into a line that connects to another and
then is reduced to one single line that goes into the top of what I think
is the fuel injector box. Can I replace this one line or do I have to
replace the whole thing?
