Leaking washer fluid tank

The Haynes manual says that I should fill the washer fluid tank up to
about one inch below the top. I did this today and was surprised to see
washer fluid running out from under the car.

Initially I figured it was due to sloppy pouring, but the leak continued
slowly.

Looking under the car I can see the bottom of the tank and all the hoses
in the area look connected. I couldn't see it, but it felt like the leak
was coming from a crack on the back of the tank. I *could* get my hand
up there.

I also noticed that the tank seems to have a black plastic filler neck
and a white tank. Is this white tank have two parts that are molded
together and have cracked or is it likely at the junction between black
and white plastic? Should I replace or remove and try to patch it up
with something?

Thanks

 

Leakage at the point where the filler tube enters the tank proper is
common, Franz. A 98 V70XC that lives in our garage has done this as
long as I can remember. The fix is to fill until the sound first takes
on a higher note, stop and just let the "excess" drip out. A few fills
and the amount lost is such that you lose very little and make
essentially no mess. One of Uncle Bob's pragmatic fixes.

Any idea how hard it is to pull this assembly out? There's gotta be a way to
apply adhesives/sealants to remedy this!

 

the over flow tube rots needs cutting off where it connects and place new
tube in
easy job
