In the electrical section of the service manual it says:-
11 to 16 kPa
1.6 to 2.3 psi.
Take the screw out of the black end of the fuel pump and slide the black cover up the power cable. Then when you look inside you will see some contacts, these can get carboned up and stop the pump from working, if this was the case scrape them clean and the pump should start working.
For Tech Questions Bike Model letters and Country are more useful than saying the year, for UK owners anyway, as registration year is not always the year of manufacturer model.
