Hello! I am need a help in such information as - manual installation ZFS on GPT in 10.3.
I tried to find some same topics, but they don't exist.
If it is possible, please help me.
If you want to do a manual ZFS install, just search for the "ZFS madness" thread on here. There's been a few changes in recent versions (such as vfs.root.mountfrom no longer being needed, but the instructions in that thread still work well).

The steps to do a manual install are pretty straight forward. You're really just creating a pool and extracting FreeBSD base/kernel to it. There's just a few important steps like adding the correct bootcode, putting the zpool cache in the right place, setting the zpool bootfs property, etc.
