Stars 150+12 Clear Fold?

[Vraket]

Tournament is at a late stage with 18 out of 450 people left. I have a stack of 30 OOO chips. A player in early position makes it 7500 to go, which leaves him with 7500 behind. I look on my cards an see AK. What is my right play?

Blinds; 1000/2000
Avg Stack; About 16k.
My stack; 8th out of 18 but place 4-8 is about one stolen pot from each other. I would probably be able to fold to the final table and I would for sure find a lot of better opportunities to accumulate chips.

So what should I?

1)Fold?
2)Push?

If i Loose this hand I will have a real though time coming back. I know he he doesn't have aces or kings but probably has AK QQ JJ TT or Even AQ.
I only have the blinds behind me and it is very unlikely that they would choose to get involved.

The player that makes the raise is good but he is also in need of chips. I get a feeling that he doesn't want a call/reraise.
