Alright guys, need a little help as I'm starting to prep for my build. Got a torn down Gen3 5.3 and I plan on picking up a 700r4 to go behind it with my np203 transfer case (keeping it 4wd). Just going with a stock build for now with plans for maybe a small cam/some head milling in the future. Here's some questions I'm having;

-What fuel pump/setup should I use?
-Any advice from anyone who's done this before?
-Anyone have a list of all the sensors I need on the engine?

Just looking for any advice or experience you guys may have. Anything is appreciated. Thanks!

You can get the later 88-91 sender and install a better fuel pump in the tank and have a return as well. Search intank pumps here. Also 4wheeloff road mag did this swap several years ago and have a good online article on it.
