Fuel Pump Noise


Gday All.
(hope I hav'nt posted this twice)

Great to see a Daihatsu Sportrack (Feroza here in Australia) forum online.

I just bought a nice little 94 Sportrack and am hearing a small whine from
the fuel pump in the drivers side rear side panel. It seems to be turning on
and off every 30 secs or so.

Is this the normal behaviour or should it be replaced?

Thanks and cheers for new year!
