Have a Hozelock pump sprayer (5L) which is 20+ years old, and no
pressure, so bought a service kit and replaced various washers etc.
However, there is now plenty of pressure, but all that comes out of the
wand is air, not a spray. Tank contains water only, for testing. What
have I probably done wrong?
Where is the internal hose that goes into the liquid and what about the
little air hole that sucks in air so it comes out as a spray?
I'm going on my old one of course makes may differ in design, but in most
the principle is that the internal pressure in the bit with air in forces
the liquid up and as it passes out of the spray it sucks in air to atomises
it, scent sprays do the same but in those cases the suction from the air
passing over the tube inside sucks up the liquid.

Thanks Brian. Just coming back to say 'Forget it!', because I had
forgotten that length of internal hose which disintegrated last time I
used the pump. Replaced with a length of hose saved from an old
aquarium, and job done.
Try turning the tank upside down. I suspect you have a leak where the
liquid dip tube joins the top of the main bottle - above the water line.
I just got a right sized Viton O ring for mine. It is really only the
big one at the top exposed to air and sunlight that goes brittle.
