2 tight players in the blinds, pretty much on the bubble of the tournament.
You have massive fold equity here and those 4.5k chips are important to your stack, particularly with the blinds about to go up. Definitely raise. I would raise enough to put them both allin, because there is a psychological difference between calling off all your chips and only some of them which I think increases your fold equity slightly and you don't want to have to call even a smallish (7k) stop and go with J8 high when you miss.
If you get called try and make a straight.
