As Tom says, just the sound of the lp circuit being pressurised by the lift pump. You can actually get a small chamber that sits in the fuel lines to stop that noise - dum-dum may be willing to sell you the one that was on mine.
Rubbing noise from the belt area could be anything, but if your steering is notchy then i guess it's probably something to do with a knackered pas pump.
