The pressure can't get too high in the system because there is a pressure relief valve built into the radiator cap. Sounds like you just need new hoses.
You might want to find an auto parts store that borrows or rents tools and have them use their radiator pressure tester to test your cap. It should open at no more than 16 psi. 14 - 15 is more common. It will be stamped on the cap.
