I too have pulsar 150 when I did from reserve it was 13 litres. I don't think reserve will be of 5 litres. May be try one more time in different bunker for reconfirmation.
The owners manual (and everything else I've been able to find online) says full fuel capacity is 15 litres and reserve is 3.2 litres. Reserve is included in the full capacity, so you're really getting 11.8 litres until you hit reserve.
