I recently purchased my own gear online. I purchased my 1st stage, regulator and octopus from Divers Direct and my BC from LP. My 1st stage reg and octo were already all connected. But my BC power inflator low pressure hose, since they were ordered from LP are not. Since I am new to diving can I do this my self ( connecting the power inflator hose to the first stage myself. Or should I have the dive shop do this. It looks pretty easy, but since I have not done this before are there any special things I need to do like torque specs or washers. Thank You in Advance.
