I have a 2.5l. After the prime, I cannot hear mine.
There are only two wires in the connector going into the fuel tank. I presume one is for the gauge, and the other is for the pump.
Sounds like some kind of ignition/computer problem. I've read of fuel pumps delaying the prime for a few seconds due to computer problem. If this logic holds true, then it's the computer that is responsible for sending the voltage to the pump to turn it on. As such, my guess would be that it's not turning that voltage off after the pump is primed.
I'm sure someone here can chime in with actual experience. If it were me, I'd look into fixing it.
