What do you mean?
2 tubes go “in the tank”
1 is the water feed in from the fill solenoid. Not used if not plumbed. But do not shorten it
2 is water out to the pump should lie in the bottom of the tank
The 3rd item is the fill level sensor which is not a tube as such but the silicone protects the electric cables. Fill switch should be 50mm or so above the bottom of the tank
Be careful when you are following “tubes” behind the boiler. Easy to get mistaken
