Diagram for connecting fuel hoses

Couple questions, you noted this was a 5.8L but it appears there was only a 4.8L or a 5.3L engine option, so which one is this vehicle?

Next you said you needed fuel line diagrams but where are you trying to connect them? To the pump? If so, I attached the info below, but the lines should be different sizes so that they only go on one connection.

Then you noted about the oil pressure sending unit. I attached the instructions on this unit, but I am just not sure if you need something different.

Please run through this info and let me know if you need more info. Thanks
