Yes, put the pumps near the tanks. make sure the power to them comes off the the ignition switch so you can turn them off with the key. If there is an under hood fire you don't want to have to think about shutting off the furl supply.

Just wondering why you don't put the battery back in the original place. I left mine there. It is sometimes a pain but battery access is not needed often and it isn't in the way. One of the things I like the best about my sixes is the easy access to the plugs and distributer dour a tune up. Also to the dip stick, fuel pump and fuel filter.

Years ago I started a thread here about my flatbed. It was mostly about the engine plan which was a turboed, throttle body injected, 292 truck. I built a megasquirt mother board to run the injection but just gave up on making it work. When I get the 292 in the truck I may take another look at it. LINK
