I ordered a tee fitting for the Window Washer on my 1990 740. When it arrived I tried to blow through it in all directions but found it wouldn't pass any air at all.
I contacted the supplier and they sent me another one. This one is the same. If I can't blow through it how could a small pump force water through it? Am I missing something or doing something wrong ?
Thanks,
