Definately sounds like a faulty fuel pump to me.
Nothing special needed (just sockets, spanners, screwdrivers) unless the pump has been replaced previously and has been soldered (rather than using spade connectors), in which case you will need a soldering iron.
Have some rags and a jar/bucket to catch any spilled fuel otherwise you will have a smelly interior for a while.
Make sure you do this with all the doors open and have adequate ventilation and avoid any sparks.
