Default Lowrance LMF-400 Reset Fuel Level? Please Help!

In 2012 I had a professional install of an electronics package in my new Sea Hunt Escape 207LE w/ new 150HP Yamaha 4-Stroke. Part of package included a Lowrance HDS-8 & two Lowrance LMF-400 multi-function gauges on a NMEA 2000 network. Boat came w/ basic Yamaha gauges. The OEM Yamaha fuel gauge was pulled to make room for one of the two LMF-400s. Goal was to have total fuel data using the engine fuel flow sensor. Install also included a Lowrance EP-65R Fluid Level Sensor. I chose the equipment and capabilities with advice from a well-established marine electronics shop and left the details / install to them. I assume that an EP-10 Fuel Flow and a memory unit were also installed, since the system seemed to work.

Current Problem: A year and a half ago I had to put the boat in storage. I had the engine winterized and completely drained the remaining 34 gallons from my 65 gallon tank. Last week I (stupidly) added 25 gallons of fresh gas before launching. Now my problem is I see no way to reset the tank to zero remaining fuel on the LMF-400 gauges. As far as the system knows there is still 34 gallons remaining. I assumed I could reset all values to zero and then do a “partial fill” on the LMF-400 gauges for the 25 gallons. After two afternoons sitting in boat (on-board battery charger on shore power) w/ manual, I still am showing 30+ gallons! (I dead reckon about 9 gallons used this spring of the 25 I put in, so I expect actual fuel to be around 16 gallons left in the tank.) I tried to access the “Reset Values” option on the LMF-400 gauge, but I never, at any time, saw the “Reset Values” option! From SYSTEM SETUP I selected BUS DEVICES > FUEL TANK > and, according to the manual, expected to see an option for RESET VALUES which, when selected, would result in the message “Press Enter to Reset Device Values”. No joy. Instead, I just get a list of the following choices: “Level Warning; UnConfigure; ReConfigure; Calibrate; Reset Cal”. [yes, I did try to scroll to see if there were more options] So, I tried selecting “UnConfigure” and got a list of choices: “Navigator; Fluid Lev Unc; Display; Unknown” I selected “Fluid Lev Unc”, assuming the EP-65R would be unconfigured. I then did a “ReConfigure” of Fluid Lev and changed the Tank Size from 0.1gal back to 65.0 gallons. I hit ENTER and got the “Changing Device Settings” message and a return to “Searching Bus Devices” > “Navigator; Fuel Tank; Unknown; Display”. I hit EXIT to get back to my fuel page to see what I had. No change whatsoever to values displayed on LMF-400s! I then tried selecting “Unknown” and got a screen with message “Working Properly, Add 1” so I did an ENTER and was returned to the same Bus Devices list.

So, I’m stumped. I have no way of seeing what my actual fuel levels are! I never at any time saw the expected “Reset Values” option! What am I missing here? Can anyone help me? Anybody have a suggestion?
THANKS!!!

Many thanks to Moonlighter475!! Apparently there is no easy way to reset values so that my tank reads as empty. I will simply use a work-around and add fuel to the tank to bring it up to the amount the boat already thinks is there.
