Outer Limits 4x4 Board

Would any one know whats up with my fuel pump? its running fine i think but even after i switch the car off it keeps humming real loud for quite a while. its a disco 1 3.9 v8. thanks.

I would check that the fuel relay is not sticking on as it should go off as soon as the ign is turned off.

In my RRC the relay is the blue? one under the drivers seat near the ECU but I do not know if it is in the same place in a Disco.
