Help Please got a leak :(

[CJ_Derv]

Hey all,

Wondering if anyone can help. If found a leak coming from what I believe to be part of the rotary head of pump, ( cast bit on right hand side ) it looks as if its coming from the bottom far part where injector line bolts onto if that makes sense. not entirely sure what the part is call or how its sealed or if its just gathering here hard to tell.

Any help or input appreciated
