His is very different....he mounted them longways.
Of course, if it was my build, I would hide the fuel pumps/ filter on a removable rack inside the left sealed/vented box instead of hanging them under the rear....but that's just me
I was talked out of putting them in the box in the trunk.......... Fuel inside the cabin is not a great idea and fuel pump's push fuel and work better below the bottom of the tank.........
