[1.7.10] Placing a block doesn't go at the coordinates I want

[Saevar]

I'm trying to place a block(specifically water/lava from a bucket) at certain coordinates.

The placement action needs to be sent from the client because I want the mod to work on a vanilla server.

 

What I've got so far places the block where the player is looking at but I don't want that. I thought this would place the block at x:1, y:3, z:0 soo... what am I doing wrong?
