2014 Seneca fuel gauge

Any one else having an issue with the fuel gauge ?? My low fuel light came on and I filled both tanks for a total of 41 gals. Would think that it should have been reading just under 1/2.
Any input ??

Yesterday the fuel gauge indicated 1/4 tank as I was only able to add 34 gallons total between the two tanks. Not sure how accurate the gauge is....

In the year long trek we made to actually pull the trigger on our own Seneca, I ran into this problem a lot. The main answer was to take it to FL and make a warranty call. The answer is vague but has something to do with the fuel level sender in the tank. Most people indicate they just live with it and keep good logs on their fuel economy. Apparently, the RH tank holds all the fuel level sensors and are common parts to the M2 series of trucks and they do not calibrate the sensor to the tank it is married to all the time. Hope it helps.

Good response. The Freightliner service manager is thinking the same thing

Oh, yes! We had the same problem with a brand new Melbourne last year. A connector had pulled apart under the cab. Have them check all the wiring connectors under the extended cab and RV. That is what finally fixed our gas gauge after trying everything else for two weeks!

Mine does the same thing. Low fuel light and 45 gallons filled both tanks. Have to get it checked out.

Thoughts. 2 round tanks max fill when empty 62 or there about. Fill caps are not on top of tanks loss of about 12 to 14 gallons. Sensor in small tank. Holds 28 gallons. Large tank holds about 34. But since it is About 15% larger and equalizes with gravity it will have 4 or 5 gallons more remaining when around 1/4 on gauge. In this thought process 1/4 or around there would take 21 in right tank and about 20 22 in Left. That is how mine works out.

By the way you need to fill both tanks at the same time at a truck stop type fill with a pump on each side.
