Dorman for the win!
Part number 692-056
I will need to switch the pump and sender wires around, probably on the Blazer side. Thinking PO switched the tan wires around at the gauge and power side.
Thank God I tested the sender before putting the tank up and filling with gas.

Another way to test a sender using any GM gas gauge. Used one of my Milwaukee 12v batteries as battery source.
Great video on how to hook up the square body gauge and test the sender.

The Walbro GCA758-2 just came in. The picture from Summit shows a connector for the pump with nothing on the other ends but it does come wirh a connecter that connects to the factory sending unit. Nice so I don't have to wire the other end!
