Default Need help identifying some things in these pictures...Thanks

what are numbers 1 and 3 in the picture of the top of the fuel pump assembly? 2 is my new return in place of the factory feed and 4 is my new return in place of the factory return.

what are numbers 1 and 2 for in the picture of the bottom of the assembly?

What is the purpose of the T block and the line that comes off the tank that connects to it? can i block it off?

What about the fuel pressure sensor? is any of that needed when you have a new return and feed line with an aftermarket fuel pressure regulator?

The T block (3rd pic) is how the FPR bleeds off excess pressure (when the FPR opens it bleeds fuel off from this line)...

you should not block it off.
