How Do I Access The Tube That Connects To Water Filter

I have an LG LRSC26923TT fridge and the 5/16 inlet tube that goes from the valve assembly to the water filter assembly needs to be replaced. I can access the valve assembly and disconnect it at that end, but I cannot figure out how to disassemble the water filter assembly. I have reviewed the exploded view of said assembly, but I still cannot makes heads or tails of how it comes a part. HELP!!!
