I do not need a new fuel pump do I?

No, but the fuel pressure sensor fits into the fuel sender on the rear tank. The fuel sender is the assembly that holds the fuel pump.

On the side tank, the fuel pressure sensor is located on the upper portion of the front of the tank assembly. The sensor is attached directly to the body of the side fuel tank.
