I've discovered a leak in the hose that goes to the livewell from the pump

Actually not sure if the hose is coming in or going out, anyway, pretty sure the leak is due to a loosened hose clamp. Due to the location of the clamp up and under, I cannot get at it good enough to tighten it

Any tricks or tips out there?
If not, how do I remove the pump to tighten the clamp and re-install
Thanks in advance.
