2. We have a pair of Walbro GSL393 EFI pumps, suitable for in or out of tank mounting though I am curious how they were tank mounted.

3. Check valves. I thought that these pumps would not free flow either direction if shut off thereby not needing check valves?

I have two pumps. No check valves. I easily maintain pressure with just one. After shutdown, it was holding pressure till the next day until I modified my pressure regulator.
