Engine/Electronics Upgrade???

Bill. the gas pump stops pumping because it is "full".

OK so fill it up and carry 10 gallons in a couple jerry cans to see how far it will go.
Then fill it up and see where your capacity really falls.

Thanks to all. The Coachmen company told me my tank was 70 gallons and the pump stops normally around 60-61 so if I have 80 gallons then my gauge is correct.

Thanks again.

"And the pump stops normally around 60-61". Could you explain this part? The generator fuel pump?

How about a Scangauge. I have one in both my vehicles and find the drive to empty function is very accurate after you have done the fuel use calibration.

Gauge may need to be calibrated if your tank holds 80 gallons.

I don't know how to ask this.

I have a 2014 Coachmen with an "Info Center". It gives me information like:
a. 543 miles to empty.
b. outside temp.
c. trip miles.
d. mileage.

Well, the miles to empty is wrong. I don't know how or who to contact to get it adjusted. I don't know where the 543 miles came from to begin with, maybe the manufactured suggested mileage, but we all know an rv does not get 15 mpg.

I have a 70 gallon gas tank and I normally get 100 miles per quarter tank of gas which equals 400 miles, but I never let the tank (gauge) get below 3/4 empty and put more than 55 gallons in the tank, so I cant trust the gauge either.

So.... who do I contact to get this adjusted?

Thanks for your help

The 2014 F53 chassis has an 80 gallon fuel tank.

If the info center says you can go 543 miles on a tank of gas that would be 6.78 mpg.

Because you don't have a generator below one fourth of a tank I don't see why anybody would let there tank get that low. I see no value in taking a chance on running out of fuel!

Tank fuel gauges don't have high accuracy and when float drops on the bottom, you still can have lot of fuel that you can't measure anymore.
I am one of those who hate pulling to the pump having 1/3 tank of fuel and in the past have tested the gauges while caring extra can of fuel.
Old VW diesel wold drive for 150 miles with fuel gauge on 0.
Modern cars have range or mile to empty scale, but in my cars it calculate current fuel consumption and what left in the tank.
So when I start on reserve it shows me 30 miles range on the street. I start driving on freeway and it will come to 60 miles.
Than I have up grade and it drops to 40 miles range.
Than I drive downhill and range change to 70 miles.
Can drive you crazy, but I know that since reserve light -I can make at least 30 miles in the city, or 50 on the highway.
Modern diesels don't like to be run out of fuel, so stretching the range is risky, but you can always stick a wire inside the big tank and see how much is left there.
Other issue is that with big tanks even 5 gallons in the tank will let the engine suck air on steep grade, or tilt.

This pre calibrated at the factory and cannot be changed.
