Mend Saunier Duval Thelia 623 Boiler Pump Top

How do i fix Saunier Duval boiler - Model Thelia 623?

I have water seapage from the pump around the top of the serrated brass cap at the top of the pump (to the fron, just beneath the air pressure valve) and where the pump connects the jubilee clip and rubber hose to the left side where water passes through.

I suspect a new pump is required, i guess, but is it easy to replace and how ?

This could be the air bleed or tighten the serrated top. T he leak on the pump outlet could be the hose or the pump spigot. New pump not required
