Installiation of windshield wiper lines in a 1968 coupe

The hose runs from the Windshield Washer Tank along the contour of the shock tower to a two connection grommet just above where the wiring harness goes through the firewall and down to the pedal operated pump near your high beam switch. It may be easier to remove the pump to see what you are doing. From the pedal pump, the hose goes back through the same grommet and over to the nozzles attached to the forward section of the cowl.

Here a couple of pictures that might help.
