 I admit I'm from the old school (Mk1), but the fuel pump is under the
car right about where the fuel cap is, isn't it? Also, if I'm not
mistaken (again), I think some noise from the fuel distributor area is
normal. If your car has a 'fuel transfer' pump in the tank itself, that
is another possibility all together. As far as the primary pump is
concerned, just remember to not let anyone tell you its good just
because it comes on or pumps fuel. I had a Rabbit (with garbage in the
gas tank) that ate fuel pumps. Several of them pumped fuel (and
apparently rather quickly) but wouldn't consistently produce the
enormous pressure (Something like 
80psi?) required to open the injectors. On some pumps the car ran fine
for 15 or more minutes & then lost all power. If I let it sit for an
hour, it'd crank & run fine again for another 15 minutes. Other pumps
felt like driving a ten horsepower car at any point.
