Fuel station on my hauler is advertised as 35gal. I always felt like it was hitting near empty on the gauge sooner than it should but wrote it off as the gauge being off. Last year I took measurements of the box did the calculation/conversions and sure enough 35gal on paper. Last trip out the tank ran empty to the point my genny died and would not pump out the nozzle. Filled it back up this week and could only get a little over 26gal in the tank. Any ideas?

Check the vent hose and make sure it is above the top of the tank. Also check that the fuel filler is above the top of the tank.

Is the pickup tube at the bottom of the tank? Is there a drain plug that can be removed to see if the missing 9 gallons are in there?

Also look thru sales material for magic words to the effect of:"THE MANUFACTURER RESERVES THE RIGHT TO MAKE CHANGES AND/OR IMPROVEMENTS IN DESIGNS & DIMENSIONS WITHOUT NOTICE AND WITHOUT INCURRING OBLIGATION.Or: "reserves the right, without notice to the Customer, to (a) change the specifications of any product, (b) improve a product in any manner that OEM deems necessary or appropriate and (c) discontinue the manufacture of any product".Or: "The Company reserves the right to change these terms and conditions at any time without prior notice."(Just when you thought you got what you paid for...oops, they even have a disclaimer for that)

35gal fuel station only takes 26gal | Good Sam Community

That is the way it is SUPPOSED to work when the gen shares a gas tank with the engine.

The gen is not allowed to use up all the gas.......so you won't end up stranded when the engine won't run because it's out of gas too.

The pickup of the gen is designed so that it "runs out of gas" when the tank is about 3/4 empty.

Perfectly normal.

Perhaps the extra space is for air and fuel expansion. Generally you do not want fuel tanks completely filled.

Fuel fill is located on the top. I previously said it was a 35gal fuel station but its actually 36gal and what I had calculated out to be based on dimensions. So I am missing about 10gal worth of fuel. Unless there is a 26gal tank inside of the 36gal tank (doubt it) I'm at a bit of a loss...

This is a toy hauler not a motorhome, it has a fuel station and generator, unless they plumbed it wrong it should be able to draw from the entire tank. Since Eclipse RV doesn't make motorhomes I don't think that is the case.

If Eclipse RV can't help you might contact the tank manufacturer to see if it's by design, but I doubt that it would be.

When I owned my Attitude I was told the fuel station would only pump until there was 6 gallons left in the tank, reserving that for generator only. I wonder if since your generator quit also maybe the generator fuel pickup is pulled higher into the tank and not reaching your last 6-10 gallons.

This is my thinking also, the pick-up tube for one or the other is not at the correct distance from the bottom of the tank.

There ARE class A and C toy haulers.
I'm only going by what I see posted here:

I'm not sure why you mixed generator stalling and fuel station not pumping. My rig has two tanks. Does yours have just one?

It's one tank.

Maybe I mis-interpreted a bit.
