The Constant Control Relay Module(CCRM)interfaces with the Power Control Module(PCM)to provide control of the cooling fan, A/C Clutch and fuel pump. The module also includes the electronic engine control(EEC)relay to provide power the PCM
The CCRM is a set of 4 relays in one module. The relays are :

1. Relay for the PCM (Powertrain Control Module)

2. Relays for the high and low radiator fan speeds.

3. Relay for the fuel pump.

4. Relay for the Air Conditioning clutch on the compressor.

Which fuse or relay is for the fuel pump on a Ford Taurus?

there is not a separate relay. It is built into something called a CCRM(constant control relay module) which is a black metal box located under the plastic cover on top of the radiator support that has all the information stickers on it. The relay module has all you relays built into it, but they are not replaceable. If a relay goes bad, you have to replace the whole box. Nine times out of ten, the fuel pump goes bad before the relay module does.
