Baxi 80e Pump leak

[sam745]

Got a Baxi80e boiler with a small leak from the pump. Just a few drops over the day and boiler working fine, but would rather have it addressed.

Coming from where the metal pipe attaches to the pump housing as highlighted on the picture, the screw is tight and pipe secure. Any help appreciated

the bad news is that it is most likely the pump Hydro block has cracked or the seal has went, not really a DIY repair unless you are comfortable with doing it , the joys of Plastic hydro blocks

And the fact the o-ring above in the combustion chamber will leak as soon as you touch the screw on the pump.

You guys must be unlucky, I swap the o rings regularly on these for a drip in that location,
2 screws and thats it.
There is actually 3 or 4 o rings (dependant on age) as the connection from block is on a barrel nipple that pulls out.
