I have used a Microflo for 4000 hours now. I have found that unless
you leave power on for about one minute after setting FOB, the gal
remaining, or the fuel used, I can't remember which, will not be
correct. Yes, it is EEPROM memory, and does not need power to hold
data, but seems to need power for a little bit to insure the storage.

you leave power on for about one minute after setting FOB, the gal
