Water supply lines from head faucet to water pump replacement

[GFB]

Hello,

Looking for some assistance re replacing my water supply lines from the faucet in the head to the water pump. One of the lines has a crack in it and is leaking so needs to be replaced. Can't reach the lines under the front berth (platform bed lies on is glued down) looking for other ideas.
I can reach the main bilge areas and the pump easily, just not forward of the bulkhead separating the cabin from the birth.

Any suggestions are most appreciated!

Thanks in advance
