Upgrade 3-wire receptical to GFCI

Hello - I have some old receptacles wired with 3-wires (red, black, white). On 2 of them the tab on the hot side is broken. On the 3rd receptacle they are actually jumpered. I want to replace them all with Cooper VGF15W-3 GFCI outlets as they are all behind my kitchen counter. How do I connect the new GFCI outlets with this wiring?
Thank you!

You can't. GFCIs can't be split into to separate circuits. A GFCI breaker on each circuit is the simplest solution.

Assumes two circuits on different breakers but would also apply to a half switched receptacle on one breaker.

Thank you for the quick response. If I double up the receptacles (use 2 GFI's) would that work?

You will need to only use one hot on the GFI. The neutral will need to be pigtailed where the circuit splits into black and red.

Thank you. After this is done, using 2 GFI's - can you think of any reason why only one would work? I have a feeling that one of the sockets in the original outlet didn't work before, but I attributed it to a bad receptacle.

You are going to need some sort of test meter to troubleshoot this.
