might be something to do with the arial or alarm, have you tried doing different things to see if it stops? things like turning the radio on or setting off the alarm?

We had a quick look at this today and are indeed suspecting the low pressure fuel pump.

Its actually inside the tank. Says procedure is roughly, 'remove rear seating bottom' peel back cutout in carpet. prise plastic access cover off. disconnect wiring. mark fuel hoses and disconnect (on quick release fittings), Using vauxhall special tool unscrew the lock ring ( will have to see what this special tool is), lift fuel pump cover away from tank until wiring can disconnected from the underside of the cover. remove fuel pump cover and collect the sealing ring from top of the tank... release 3 retaining tabs by pressing them inwards then lift the fuel supply pump out of the tank. Also check the fuel filter whilst its out too.. refitting is reverse of removal!
