Yes they are using Martin-Baker PRM4-1.
SOP is jettison tanks but sometimes these emergencies happen over cities and pilots have to make certain decisions, Its takes hardly a sec to decide what to do and in the sec you can save your self or the fighter or the people down below. What I have seen during my service pilots have died saving civilian population below they could have easily saved them selves by dropping the tanks but they didn't.
My student Air Cdre Late Hameed Qadri Base Commander Kamra died just because he was trying to take the fighter away from civilian population but during that his fighter went inverted and crashed he could have easily ejected but he didn't. It was not that he was not a good pilot he was an excellent pilot on a routine western CAP near Afghan border Qadri intercepted four SU-22 aircraft. His missiles failed to launch he managed to shoot two SU-22s with his guns.
