In trying to get my coach out of storage today, it seems like the fuel pump has given up the ghost and won't pump fuel. The coach was sitting near empty for over a year ( inside storage, so no propane or gasoline ), and I wonder if things dried out. With a squirt of fuel into the carb, she fired right off, but the fuel filter was dry after a lot of cranking, so no gas.
Has anyone successfully driven their coaches using a portable marine type gas tank sitting in the passenger footwell? Does the fuel siphon down into the carb OK? I have about a 45 mile drive to get the coach back home where I can work on things easier.

The wheel well liner is easy to take out. Might be able to change the fuel pump pretty quick where it sits. I started the CanyonLands on gravity feed once, but didn't drive it anywhere or run it any higher RPMs than fast idle.

I forgot to mention, if the fuel pump failed, it might have dumped a bunch of gas in the oil. Change the oil after you change the fuel pump and before you run it.

As I recall Robin used a portable tank to drive his coach home from the storage yard, but I think he still had a functioning fuel pump. You might need to rig a small electric pump to make it work.

I think quite a few people have done that. You may want to try and let it run this way for a bit and then hook up the pump again with the float bowl full so it will idle for a while to see if the pump will start to pull at that higher RPM--the internal check valve is probably dried out.

Thanks for all the replies! Changing the oil is probably a good idea, though I don't think the pump was pulling any fuel through the lines from the tanks.

About 10,000 miles. Do yourself a favor and use an electric pump. I have found the fuel system is the biggest issue weak point of these girls. Don't half ass it. Do the tanks, lines, filters, pump and carb at the same time. Just my opinion

Chances are you think it's just a pump and you'll replace it and find it's the lines. You drop the tanks and do the lines and debate metal lines or rubber and put it back together and realize the carb is full of crap. Then the thoughts of fuel injection will undoubtably come. To mind and you'll have the drop uour tanks again for I tank pumps and return lines along with all the other equipment. I've spoke with both bounds and kanomata and they both said tgat a properly tuned qjet and fuel system will preform as well as any fuel injection. Again just my opinion

An easy way to determine if the pump is bad would be to disconnect the rubber hose that connects to the inlet of the pump and extend the hose long enough to reach into a gallon can full of gas .if it pumps gas into the carb the problem is between the tanks and the pump.

Getting home in a pinch is a lot different than the permanent fix. Take the suggestions accordingly. I'm surprised no one has told you that the tires are dangerous and you are subject to millions of dollars of lawsuits.

We did put a tube into same gas, and the pump didn't seem to be sucking the gas up, just a bit of back and forth on the fuel in the tube. I had all the fuel lines replaced four years ago and the tanks boiled out, but with today's ethanol laced fuels, anything is possible.
The pump should be easy enough to replace and we'll see! And yes, it does hurt to see six tires with plenty of tread, but old build dates!

Wow--your system should be in top shape after just 4 years. I'm sure you will find a solution easily. I really doubt ethanol is related to your problem if you have a problem Good luck and I suspect you will have it running soon !

George, I have started and driven several coaches with a 5 gallon or several 5 gallon gas cans.
Before you do that, remove the gas cap and get an air hose and a rag. Pressurize the tanks slightly with the hose and rag while attempting to start the engine. If it starts remove the air and see if it stays running. Many times the pump has just lost it's prime and can not suck the air out of the lines to get fresh gas out of the tank. It is a long way back to those tanks.
If that does not work, slide underneath the coach and remove the hose on the input side of the fuel pump. It is one hose clamp. Set one one full 5 gallon can of gas on the front bumper and hold it there with two bungi cords. Now run one gas line from the can down to the input side of the fuel pump. See if it start that way. If not then fill the hose with fuel and stick it back in the 5 gallon on can and try again.
Changing that pump in the field is no big deal. The biggest problem is the lower radiator hose is in the way and you have to work around it. I have changed two of them on other people's broken coaches. It is only two bolts and two lines.
Where is the coach. Do you want me to come up there and help?

Ken, thanks for the offer and the hints, definitely worth trying! I think that it is very possible that we lost the prime at the pump and will try to pressurize the system to fill the fuel line to the pump before we do anything else.
My coach is up in Woodstock, IL at John Lebetski's place. Indoors with a sealed concrete floor is as nice as a hanger! We should be able to swap out the pump fairly easily, and our main problem will be scheduling a time to do it as both John and I are involved in other car events (John is heavily into Turbo Buicks and I'm a long time Porsche Club member) and there are quite a few events coming up very soon.

I just looked and it is 115 miles up there. It would be a good reason to take a day trip. Just yell if you want me to come visit.
