My fuel problems solved!

Hi. Just thought i'd let everyone know, after posting with my fuel probs the other week, what the trouble was in the end.
 Apparently, it was an electrical problem, which was affecting the ability of the fuel being pumped from the one in the tank, to the external one next to the tank. Was something to do with a fuse,apparently. All my buzzing and humming noises from the pumps have gone now and its running great.
 Am wondering now, if i really needed to change those pumps and fuel filter. Oh well,at least shouldnt have any more probs with fuel system.
 Just thought you'd like to know.

Regards
Nik

Where was the fuse? Was it in the fuse box or located elsewhere, I have noises and funny performance but all obvious fuses look fine.
