Advice installing new fuel pump

[Uncle Redhead]

So I got my new Delphi fuel pump for my 94 K-1500 and had a question? The two fuel lines below have an O-ring already attached to them and they give me two O-rings in the package too. Where do the two O-rings go in the package? They gave me instructions but they appear to be for mounting a fuel pump on the sending unit. I bought the whole assembly I believe. So other than making sure the tank is clean can I just put the large O ring and locking ring over the fuel/vent lines, set the unit in the tank and install the O-ring and locking ring? Should I lube the O-ring? Looks like all the connections match what I had on my old pump. I also bought a new external fuel filter to install. They mention installing the strainer. I believe that is already on the pump pictured below correct? Any advice would be appreciated.
