HF Fuel pump question?

[nos_zc_36579]

So I got a hf crx(with dohc zc) right, and i was wondering if i should upgrade my fuel pump? since it being a hf i would think it has smaller pump than the si, and there are some good deals on ebay for walbro 255 for 99$

they all (DX, Si and HF) use the same fuel pump
