I ordered the recess plate from Summit ($50) and will take a shot at putting in on my tank. Based on the pics, buying the tank already set up from Tanks Inc would've been the way to go had I decided on the EFI route sooner (cue "If I only had a brain" from Wizard of Oz). Assuming I don't totally embarrass myself on the install, I'll post some pics on my build thread when I get to it.
