Hey, sorry, sometimes I see the alerts and end up getting side-tracked before I can reply.
I have some fuse holders and relays all by the battery as shown. Relays are under the battery, there are two. I used a 30A fuse and a 70A relay for the fuel pump as its an Aeromotive A340 which supposedly draws 14A. The third fuse is an additional 15A to protect the injector harness independent of the fuel pump and it's after the relay so they turn on the same way. The ECU fuse is 2A.

The circuit is basically this from the manual except I have an extra fuse as mentioned on the injectors due to the huge fuel pump and not wanting to run huge wiring back there.
I didn't do a highway run yet, but just local driving (some stop and go, 45-55mph roads mostly), its in the 15-16 range with the T56 magnum transmission. So with a regular 4-speed it was about 14. Between my job and the pandemic it hasn't gone on a real road trip though I may go on a leg or two of Power Tour this year since its not terribly far away.
