an hour and a half is not an unreasonable time at all. I doubt most people could do it any quicker. If you think you can do that job under that time , start the clock and walk up to the bike and do it and time yourself. While your doing it make sure you don't scratch the guys bike or spill his fuel out, leave the pump assembly seal leak under the tank etc etc. AND make sure the fuel gauge float is not bent on reassembly...........
