Fuel Pump Issues

Evening all,Had a problem today with the ZXR750.
Was riding home when it died and wouldn't fire again.Turned out it was the fuel pump.A bit of side of road repairs got me going again,but the pump's shagged.
What I want to know is,is there an after market pump avalible from like sprints or repco that will do the job,or is it better to stick to genuine.
Does any one know what pressure and volume these pumps need to put out? Bearing in mind that its a 1991 model bike.
Cheers,Frosty.
