Fuel Gauge

Yahoo Message Number: 63654
Just fueled the coach since I was heading to a remote area, the gauge was indicating 5/8 to 3/4 full, it took 70 Gallons? Is this normal or is the gauge going? John Tanzi 05 Allure

Hi John,

Our fuel guage started giving us a reading of more fuel than we had in the tank after about a year of use. It almost always showed full to 3/4 tank. The sendng unit in the tank had failed.

Clearly this is a problem as we also have a bad gauge. Gave up trying to use the instrument and now track miles driven. We set the odometer to zero at each fill and look for fuel after 500 miles. This allows a good cushion before running out.

Those gauges are imprecise at best. If your tank is like mine, 70 gal. is a little over half so your gauge was reading a little high. Even when registering properly, my gauge jumps around with the slosh so the information is next to useless. I use Silverleaf extensively as it tells digitally how much fuel has been consumed - therefore how much is required to fill the tank. It is always within a few gallons of the actual fill.

A word of caution when using your trip odometer to judge mileage between fuel stops, be sure to factor in generator usage while moving and sitting. Even a half gallon an hour will drink up some diesel, and you'll be surprised how low on fuel you really were when you thought you had another 10 - 15 gallons.

Some of you may recall we are rookies with our Allure. After reading that the gauge can sometimes be suspect. We write down the current miles, and gen hours, at each fill up on our first big trip. Suspect more seasoned owners just estimate the gen hours consumption. I'm using 1/2 gal for each hour. On the last trip, we had three fill ups, with a half tank remaining by the gage when we got home. I like to keep my trip odometer running during the full trip.
Those three fill up's, seemed to indicate our gauge is pretty accurate so far. I'll do this another four or five more times, then if the gauge does continue seem good - forget about it until/if it becomes a problem...
Got a kick out the recent timing on the Oil Gauge, as I was seeing spikes up to close to 100PSI a few times. Freaked me out, until I saw the SL showing the constant 55psi. Will play with the Oil Gauge during the down time ahead:)! Best,

intrigue10676 has an interesting point. Practically speaking, anyone running their fuel tank down to within 10-15 gallons of empty is asking for trouble.
Generally the generator line into the tank only goes down 3/4 so the generator would stop before you got 10-15 gallons from empty. Also, at almost empty you would be in jeopardy of pulling into your fuel filters whatever slop is at the bottom.
I fill up when I estimate I've used 90-100 gallons from my 135 gallon tank.

Hi Smitty . . . here are a few tips you may not be aware of.

Your SilverLeaf may have the following functionalities -
* Fuel consumption read by the Silverleaf is engine only. Reset one of you tripmeters every time you fill up and you should be able to guess within 1 gallon of diesel to fill up next time by adding the SilverLeaf readout of gallons used plus 0.5 gal X hours the genset ran.
* Zero the other tripmeter at the start of your trip and then read out the MPG for the whole trip when you get home.
* If you have a Daily Log screen you can read miles traveled, MPG, hours engine ran for that day.
It is a good habit to go home with a full tank of diesel and minimal air in the tank. Also, depending on weather condtions, one or more of these can happen if your coach will sit for weeks/months -
*With daily temperature swings, over extended periods, the cooling/heating of air above you fuel in a 1/2 empty fuel tank can condense water vapor, which settles to the bottom of the tank. There is a fair amount of water vapor in 50 gallon of humid air, and the day after day cycle adds up.
* If its winter put in a dose of fuel stabilizer * If its summer/hot, add a dose of biocide
The neat thing is all these preventive actions cost next to nothing . . . just good habits.

Lee,

Am I missing something? Does the fuel line for the engine not always pull from the same spot at the bottom of the tank?
