I have purchased several meters of the nylon webbed wiper fluid line and the valve that goes between passenger and driver side lines. I will do this while replacing the hood pad.

I have a wagon and need to replace the line going from the reservoir under the first aid kit to the nozzle above the hatch glass. Mine has a crack where the hatch hinges.

I am just wondering how I connect the line to the nozzle. Does the window need to be out for this? How does one route the line? Does the headliner have to come down?

Thank you very much.
