How to draw a fluid in a gui? [UNSOLVED] I either crash, or nothing happens...

[TheEpicTekkit]

So I have been trying to draw A fluid in a GUI, and I cant figure out how... I want it to be able to draw the fluid from any mod with the correct texture.

 

Any of my attempts so far have ended with a nullPointerException, or id doesn't work at all, and nothing ad drawn in the gui

 

Any help?

IIcon icon = FluidStack#.getFluid().getIcon();
	Minecraft.getMinecraft().renderEngine.bindTexture(TextureMap.locationBlocksTexture);

        tessellator.addVertexWithUV(0, height, 1, icon.getMaxU(), icon.getMaxV());
        tessellator.addVertexWithUV(1, height, 1, icon.getMinU(), icon.getMaxV());
        tessellator.addVertexWithUV(1, height, 0, icon.getMinU(), icon.getMinV());
        tessellator.addVertexWithUV(0, height, 0, icon.getMaxU(), icon.getMinV());
