Has anyone had experience adding a 8-10 gallon generator fuel tank? SHE
wants to have a seperate tank for the generator (with a manual selector
for the main tank). The GMC ran out of fuel during one of our 8 day
power outages and SHE wasn't pleased...
The next problem to tackle is finding out what happened to the 3/4 tank
I had last summer. I doubt anyone stole it (like someone did to my late
father in laws heating oil!) No smell that I could find. It was
facing slightly down hill though when the bags partially deflated it
was pretty level. Can it evaporate that much or should I be thinking
about lining the tanks? Have not really used her since 2009. 4 of the
tires are are 11 years old and the mice have moved in. What was I
thinking? Use it or loose it!

If I where to set up the RV generator to double as a stand by emergency generator, I would use a outboard boat gas tank. they come in relatively easy to handle 5 or 6 galleon sizes. Just set it next to the RV and run a fuel line to the fuel pump.
You would not need to move the rv to fill the tank.

This is a boat tank:

Even if left in the rain, water will not get in the gas.
I think it cost about $20. (I used it to limp my '77 home.)

The ONAN fuel pump easily pulls fuel up to the ONAN from a tank placed on the ground (as long as you remember to open the tank vent).

Ron, your generator feeds fuel from the rear (main) fuel tank. The pick up
tube only goes 3/4 of the way down in the tank, and if the nose of the
coach is low, the fuel in the rear tank can and does migrate to the front
(aux) tank thereby lowering the level in the tank. Keep your tanks full
when you are storing the coach. If storing long term, add a fuel stabilizer
to it. If your coach is a Coachman upfitted coach, then sometimes they
splice into the fuel line from the Main tank instead of using the fitting
in the tank. If that is the case, it could drain your rear tank. Probably
be a good thing to crawl under there and verify what you have, and check
the condition of the fuel hoses while you are at it. Fuel lines are like
food. If in doubt, throw it out. You really, really do not want your GMC on
fire.

Its not the generator that is running us dry, it is going dry from
sitting. The Honda EV6010 used only abour 5 gallons in 8 hours out of
the gas can. It was only running 4 or 5 hours on the GMC tanks which
were supposed to be 2/3 full (okay, a year and a half prior it was 2/3
full. Started and brought to temp maybe 10 times since then. SHould
not have drained 2/3 tank...

Ron, there have been many times that I was convinced someone was stealing fuel from my GMC. What I think is really happening is that because of the flat nature of our tanks and the fact that they are interconnected, any slight change in attitude appears to cause an inordinate amount of gage movement. Also, I have managed to restart both the coach and the Onan, by changing the side to side as well as front to rear balance of the coach.

This time, when Julie put about 8 gallons in the GMC tank, it started
and ran for 15 minutes. I started it on Saturday and it died after
maybe 2 minutes. 8 gallons should last more than 17 minutes,though it
seems to go that fast in my Excursion!

That is a serious consideration. The fuel lines other than those in the
front of the coach are original as far as I know. If I am going to
replace the rear, I might as well drop the tanks, line them and put in
new senders and sock. Maybe the senders will support my new fuel gauge!

New fuel lines are definitely a good idea but my experience has been that any leak near the top of the tank will definitely be smelled inside the coach.

Regarding gauges, I know I've seen posts suggesting you really only need one gauge since until you're down to about 1/4, they both read the same since the tanks are connected (assuming the coach is reasonably level). After that you should be looking for a station anyway.
If you want to put in in-tank fuel pumps to, among other things, reduce vapor lock problems, check Jim K's site. He has a setup.
