1998 V6 INTAKE MANIFOLD

I HAVE A 1998 FORD RANGER 4X4, V6. I HAD ONE OF THE METAL TUBES ON THE TOP OF THE INTAKE MANIFOLD BREAK OFF. THERE ARE TWO TUBES. THEY HAVE WATER LINES COMING FROM THE HEATER HOSES. I GUESS IT IS FOR CIRCULATING WATER THROUGH THE MANIFOLD. MY PROBLEM IS I DON'T KNOW HOW TO FIX THE PROBLEM. IT LOOKS LIKE THE TUBES WERE PRESSED FITTED INTO THE ALUMINUM MANIFOLD. I NEED SOME HELP.
