Fuel Pump Noise R1100 GS 1999

[Nomadusa]

My fuel pump recently bit the dust. I am out in West Africa (How normal is it for a fuel pump to go after 8 years, 30000 miles, maybe bad gas here in West Africa?). I got one off another R1100 GS 1999, same year, from the USA. It works, can start the bike nicely. Replaced the O Ring, and put in a new Fuel Filter for the used pump. I noticed my old pump had a lot of metalic shavings. It must be rust from the gas filler cap. Tank looks very clean.
Anyway I hear the normal fuel tank whine when I start it. But I don't remember it being so loud when I click into first gear and drive off. When I rev the engine I can still hear the distinctive whine in the tank. It sounds pretty consistant. Not much fluctuation that I can tell. I have taken off the Cat Converter, and put on a racing tube, so it is pretty loud. But I can still hear the pump. I imgine if my helmet is on I would not hear it.
I am wondering if this pump is OK, and the loudness is nothing to be concerned about.
I take this bike up to some rural areas in the West African bush, alone, and I can't afford to break down up there. I don't have a film crew and Charlie watching my back.
It has been a month since I broke down and finally running again, so I may be over cautious with the odd noises I hear. I have been a little cautious since my Hall Sensor unit gave me a scare once and I was down for a week.

Cheers,
