You may want to post in the Monaco Owner's section in IRV2. I know some have done the mod of changing out the pick up tube and where to order it from. It's on my to do list as well. Mines shuts down right under half just like yours and understand your complaint.
Doesn't sound like a serious problem to us anyways. If your a Handyman type, then fix it, if not then have it fixed, or live with it. Thats about your only choices. If it has always been this way, then the Manufactor probably put to short of a pick-up tube in your Fuel Tank. If it is something new, then something has changed, which means you still neeed to fix it. We do mostly all Boondocking, so fuel isn't an issues for us, as we fill up as close to where we are going to be Boondocking anyways. Some times we wished we had your large Fuel Tank, as we only have a 75 Gallon Tank. But I fill up at half a tank anyways, as I have a very bad back, and need to get out and walk around by the time we hit a half a tank, so that is not an issue for us either. But we never worry about how mmuch Gas we have in our Motorhome, as we do carry a Twin Set of Honda EU2000i's also, so we always have a spare can of Gas for them. We also take our Toad with us every where we go, and the Gas Tank on the Toad is always full also, so we could get gas out of the Toad if needed also. We carry a small Travsfer Pump, if Gas is needed from the Toad. Not having enought Generator Power, or Fuel is never a problem for us. But we wish you well, and hope you can fix this one yourself, as it can't be all that hard to installl a new Fuel Line into the Tank, unless you have to drop the tank. Are you sure that your Float in your Fuel Tank hasn't developed any problems, affecting the Fuel Guage Reading. Good Luck. Happy Travels. Dan & Jill
Thanks, tomgagne, your response was exactly the information I was seeking. I didn't want to risk breaking off the fitting screwed into the top of the tank only to find out their was no practical way to lengthen the pick up tube. Knowing now that its possible, I think I will move forward.
Just an update to my original post. Armed with the valuable information gathered here, I decided to tackle the modification to the gennerator pick up tube. I pulled the fuel line from the top of the tank you all told me was most likely the gennerator supply, the furthest one to the right (back) on the driver's side. I removed the fitting from the top of the tank and pulled the pick up tube out. Instead of ordering a new tube sight unseen from Monaco, I took the tube I had to NAPA to compare it to what they had. The parts guy suggested a fuel pick up tube repair kit for about $17.00. The kit included a plastic tube which was the same diameter as mine.(5/16 ID) Using a utility knife, I cut the old tube off the fitting. I warmed the new tube with a hair dryer to soften it a bit and pushed it onto the barbed fitting. (the directions said to soak it in hot water for 10 minutes. That didn't work to well, so I went with the hair dryer.)
I determined that with the original tube I had about 40 gallons of fuel remaining in the tank when the gennerator ran dry. Based upon the size of my tank, I calculated that it holds about 6 gallons for every inch of depth. I cut the new tube 3 inches longer than the old one. This will give me access to another 18 gallons of fuel and still leaves over 20 gallons exclusively for the engine in the unlikely event I run the tank low.
I'm thrilled to be able to stretch the distance between fuel stops by a couple hundered miles and still be able to run the gennerator. I would highly recommend this project for anyone looking to acess more generator fuel.
Thanks to everyone who responded.
Hey "Congrats" molery. Doesn't it feel great to solve and fix your problems yourself. Look at all the money you saved yourself by not taking your Motorhome into a "Repair ( RIP ) Shop". And if your still a bit off, you always know that now you can add to it again if needed. Hope all works out great for you. Good Luck. Happy Travels. Dan & Jill
I had the same issue on my last coach. Its not a big deal but a real pain in the butt. I did nothing about it and learned to live with it. I was told by Fleetwood that they could drop the tank and adjust or replace the pick up tube.

I pulled mine out a few weeks ago. It was a metal tube soldered to the fitting, so couldn't do what you did. Mine shut off while I was driving at about 3/8 tank and was gonna lengthen it, but when I measured it, it looked like it would actually go lower than 1/4. Must have sucked air due to fuel sloshing around. Did you measure your's and compare to depth of the tank?
