Apologies for the confusion, you need to join both pipes together otherwise your cooling system will empty rather quickly.
Either use an appropriately sized piece of copper tube to join them or I think you can remove the pipe on the right altogether and stretch the longer pipe on the left to connect to both engine side connections.
It should be noted that whatever you do the cooling system should be secure. If a leak develops it has the potential to damage your engine.
thank you for that mate ill crack on with it in the morning
