Washer Nozzles Options

[yeahmag]

Seems like there is some wild pricing from cheap to expensive on replacement washer nozzles for the 914. Anybody have a recommended replacement?

What do the check valves under the nozzles check? Are they necessary? There appears to have been a change in the nozzles in mid '74. What is the difference in the earlier ones and the new and improved later ones? Are they interchangeable?
I switched my pneumatic system to an electric pump system. Would that make a difference? Any thoughts?

I believe that the check valve is to prevent the low pressure area created by the windshield from siphoning out all of the windshield fluid especially at high speeds.

Actually, the base of the windshield is a high pressure area. That's why the fresh air intake is there (and why cowl-induction hoods were invented).

The check valves are to keep the washer fluid from draining back into the reservoir, which would cause a delay in squirting when the washers are activated.

Alright. This is what I've found out. Old style versus new style:
Old ones are chrome and better looking (small details count). Much more difficult to install. Have a female end for the check valve male end. Are much more expensive.
Newer style: Much easier to install (they snap right in). Aren't as good looking. Have a male end to attach the hose to with a check valve installed somewhere between the reservoir and nozzle. Are slightly smaller in circumference so if your car has been painted with older style installed, a small ring of old paint will show. Are less expensive.
I have a '73 2.0. I could not get the old style to seat properly no matter how hard I tried (including lubing with soap). I installed the later style with no problem. They were easier to hook up and snap into place. System works great.
