1963 Corvette Windshield Washer Hoses ID, OD, and Routing

If I remember correctly the large hose (suction line) comes from the reservoir to the pump.
The smaller lines from the pump to the nozzles. The large line will not fit through the rubber grommets in the firewall well.
I have the original lines still and could check the diameters and length(s) if you still need more information.

Also, on the original one piece units in a 63 the check valves can be removed, cleaned and replaced. So if you have a broken unit ( plastic body ) you may be able to swap check valves. I did this to fix one of my problems,

Good Luck.

What was your method to remove those metal "cages" without damaging the plastic? I tried gently "picking" at them, but was reluctant to start grinding.

Chuck,
Before any disassembly try some hand lotion on the rubber check valves to soften them up a bit.

I pushed them out by going through the nipple. Think flat head punch.

I tried mineral spirits. Nothing to lose by trying the hand lotion.

Worth a try. One is easily accessible. That's the one from the reservoir. The other two, the ones that go to the squirters.........not so much. The cages would have to be pushed out from the front to get to the fronts of the flapper valves...

The suction line measured 13/64 ID. The 13/64 drill just slipped into the hose. It easily went in past where the old hose had expanded where it had been on the nipple so long. So I suspect it is designed/designated as 1/4" hose.
The hose is 24-7/8" in length.


A couple of other pictures. The wall thickness is thinner than most across the counter style hoses one would normally run across.


I attempted to get a picture of the ribs, didn't turn out very well but I will post it anyway.



This was the only hose I found.
Unsure what happened to the pressure lines as they are lost to history.

The reproduction hose, as supplied, was 31" long.
