Are you talking about useable fuel they will hold 208 gals but you can use only around 190 gals before they stop some a little more and some a little less mine will stop at 188 gals used and gauge shows fuel btdt

good luck

Good timing Gil, I’m adding a similar question..

I have 250 gallons, 160 and 90 and last week I ran it down to
empty on the gauge intentionally. When I fueled, it would only take
158 gallons. So in theory, I had 102 gallons left, but we know that
is not all usable.

The gauge would be in the main 160 gallon tank and I would think
the two tanks would equalize as the fuel is used. So I assume I have
lots of fuel remaining when the gauge reads empty, but how could I
confirm that other than trying to dip the tank? Running the gauge
down to empty is too stressful, so I won’t be doing that again, but
it would be nice know FOR SURE if there was plenty of fuel left.

I always lean the bus to port when fueling to make sure it’s full.

I think everyone needs to understand their fuel capacity and set limits. Nothing sucks more than to run out of fuel.

I am still learning the current coach and have not yet been willing to go beyond 1000 miles. My current average over 3000 miles is 6.1 MPG. I am supposed to have 208 gallons capacity which represents a real capacity of about the 190 gallons Clifford states. Using a conservative 5.5 MPG a 1000 mile distance will require 182 gallons. At my real mileage I should only require 164 gallons. Both are below the capacity so theoretically I am OK. So far no low fuel warning light.

On the previous coach I once took on 235 gallons in a 298 gallon capacity and that did not show low fuel warning.

Tom,

The effective empty is another great question. Clearly you have a lot of driving you can do if you have 102 gallons left when the guage is reading empty. What would be great to know is the dimension of the tank, 2 in your case, the measurement of the fill opening from the top of the tank and the length of the pickup tube. In your case with two tanks you also need to know if the tanks are set on the same horizontal plane, which they likely are, and the location of the lower equalization hose.

Many say just mentally calculate fuel used. I have a ProDriver, which is pretty close if I don’t run the generator. But running the generator throws the numbers off. What I find myself doing is refueling way too soon. With my new dash I hope to gain more trust in the reading. On my my first fill the guage said I had 111 gallons of fuel left, which was off by about 30 gallons. Once I get the gauge calibrated I think I can get the accuracy improved.

I have also had problems trying to figure out the usable fuel. I have a 40′ CC that has two tanks. I am going to say 160 and 90 gallon. Thats what I have been told by numerous sources. I have the Silver Leaf glass dash which has had a fuel gauge problelm since day one. I installed a manual Prevost gauge and disconnected the Silver Leaf gauge to try to get more accurate readings. When my readings are around an 1/8 of a tank I can stop and fill up and only take around 190 gallons. On a 250 gallon tank, 1/4 of a tank should be about 62.5 gallons, right. I have run it dry before and only put in 212 gallons. The Prevost gauge doesn’t seem to move till you have used about 100 gallons, so doing all this math keeps me confused. I am guesing the fuel pick up for the engine will not use all the fuel but leave somewhere between 1/8 and 1/4 of a tank. None of this is taking into account any generator use. My info on the generator says it will stop running at about 1/4 of a tank. I can fill from either side of the coach and when I fill up, I fill to the neck and wait for the air pockets to clear out. (I think) From under the coach I have seen the two tanks, one big tank and connected with about a 2 inch hose is another tank which runs what looks like between bays from one side to the other. Any thoughts??????

With the former Country Coach we experienced two (2) failed tank units. It does get the heart pumping pretty fast. Now days I use the quarter tank rule along with noting the mileage when I fuel up. Seems to work and a lot less stressful.

Had the pleasure of sitting dead stop on the Interstate for 3 1/2 hours early this year. You never expect it to happen but when it does the first thing you will check is fuel.

While parked on the Interstate actually had someone knock on the door asking if they could use my toilet.

Yeah…. what toilet????

Everytime I top off my tank at the corner fillin’ station by prepaying at the pump with my debit card it seems to always stop at $50. Funny how I always seem to need only $50 in fuel. 🙂

I always go mile driven. As soon as I hit 800 miles I start looking for an loves truck stop.

I try to fuel every day when I am traveling usually in the afternoon, like to keep it topped off, you never know, I hold 235 gal and when my fuel gauge is on 1/2 it will take 95-100 gallons, most I have ever put in at one time 170gallons equates to 1,000 miles { +-} or two days hard driving Gary

For reference, today I put on 241 gallons on a 298 gallon capacity with no fuel light. We are averaging 7 mpg w/o generator time.

Dan What did your fuel gauge read before fueling up? Rick

[Archived]

It was reading about a needle thickness away from empty.

I have let the fuel light go on once several years ago, and it took about 260 gallons but probably burned about 10 more gallons after the light went on before stopping to refuel.

If you have a 160 gal tank you are not going to get 160 gallons into it. I believe the filler is designed to only allow you to fill it to the 85% level. Therefore you are always going to be short 24 gallons unless you are creative in tipping and shifting the bus.

The sticker on mine says 95%.
