Washer pump help needed
 
Hi guys. I am trying to replace the hoses for the windscreen and headlight washer system on my '69 vert, but I'm having trouble identifying the connections at the washer pump on the cowl.
I have the assembly manual, but this area is not very well defined.
Has anyone got a schematic of the inputs/outputs, or could be so kind as to take some pics of both sides of the wiper motor/pump so that I can figure this out?
Thanks in advance!

Of the 5 ports, the center is the feed from your reservoir that feeds one piston. The other 4 are the outlets for windshield and headlights. The 2 closest to the firewall are windshield. You did not ask, but in '69 and '70 they had water check valves very close to the headlights. In '69 they were all black. They will be the hardest parts to find unless you are lucky to still have them. White barrels shown are '70's.

This should help you. 69 is the only year that uses the 3 port washer pump and the anti drip valve. Later years use a five port washer pump. Letter F is a check valve. Letter G is nearly impossible to find, but any Y fitting will work if you are not concerned with originality.
