Leaky water tank (1 Viewer)

Afternoon all
My freshwater tank is leaking on my Elddis Suntour 140.
Next to the fill hole there is a blue pipe attached to a flexible elbow to a tank connector. This is my leak, the rubber seal has perished!!
Now... question is??? How do I replace the gasket without the connector falling in the tank causing a complete strip down???
And??? What is the blue beast anyway?
Please remember I am a clumsy old git!

Push a stick in with a piece of string attached then you always have the connector. Hold the string while you change the gasket. Break stick and remove.

It's probably a tank breather. Is there no access/inspection cover into the tank?

Hi
The tank is under the floor with no access without complete removal?
However, the idea of the stick is perfect.
I’m pretty sure this is the outlet pipe for the water system? Pump being external, yet to be located!!!
