fuel system question

I found the main hard line from the fuel pump to the front of the truck brittle and leaking right down beside the tank. I followed it up towards the top of the tank to the pump and it can't be replaced. So I took the tank out and removed the cap that holds the pump on top of the tank with the hard lines on it. I need the part that the pump bolts to, it bolts the the top of the tank with little bolts like a cap with a leg on it that runs into the tank that the pump is on and the three hard lines that are fixed to it. What am I looking for, I can't find it anywhere.

I forgot to mention it's a 89 4x4 22re fuel injected
