This is just my suggestion of what I would do. I would drop the fuel tank and clean it out the best I could and then put a sealer on the inside of the tank and slosh it around the entire inside, reinstall tank and clean the rest of the fuel system and drive on. You can google fuel tank sealer and even see people do the process on you tub. 

Hello Deborah, whats your year and model #?

a 1988 class a 31 ft winnebago

model number iswcm31RQ

sorry wrote that kinda funny model number WCM31RQ

Just exactly like Dwayne mentioned. (he beat me to the suggestion)lol.  I have dropped the fuel tank, and visually inspected it for MAJOR rust issues. If  it wasnt to bad, (salvageable). I would take Dawn brand dish soap and warm water, and heres a trick,, Dollar store MARBLES. Yes marbles. Pour in a bucket, (I use a 5 gallon bucket with a good spritz of dawn dish soap. Add the marbles, slosh it around, on its sides, every which way you can. (The marbles act as a slight agitator and the Dawn dish soap breaks Gunk up). empty out the tank, Re-rinse a couple times with clean water till the bubbles are gone.Make sure ya get the marbles out. (I usually use 12 marbles,so I can count them when I take them out and make sure I have all of them). On-line.. They have Tank sealers. Looks like Syrup. You pour that in (after the tank is well air dried out). Roll the tank around to *Coat the inside of the tank. (Follow the instructions that come with the sealer). Re-install the fuel tank and install a fresh fuel filter.

As Dwayne mentioned, YOUTUBE has a few Video's as the process of using tank sealers.

Ya hafta love the ole internet.    Good luck..

As far as replacement,, Shopping around via Ebay will give you an idea of whats available.

There are several companies that have replacement tanks and even aux. tanks that serve the same purpose.

Good luck.

Hi Deborah,

We bought a 95 34RQ Itasca 2 1/2 years ago and had a very strange fuel system problem. We have the Ford chassis (John Deere on your coach). After driving it about 1 1/2 hours it acted like it was starved for fuel (plugged fuel filter/fuel line vapor lock) The previous owner carried a spare fuel filter in it so he had been experiencing the same problem. I replaced the fuel filter and used an air hose to back blow the old filter into a towel. There was no dirt or rust. I did an internet check and found there had been a recall on the fuel pumps in a lot of years of the Ford chassis. Our motorhome has only 26k miles and Ford was no longer providing the extended warranty coverage on the fuel pump. The fuel pump lives in the fuel tank. I ordered up a new fuel pump and spent 4th of July 2013 pulling and re-installing the fuel tank. The inside of the tank was pristine with no sign of dirt or rust. I don't recommend doing this alone! All works great now and for the past 4500mi.

 

None of my story applies to you if you have the Chevy chassis or if you have already identified you indeed have rust plugging the fuel filter.

 

Hope this info helps you or someone else. By the way Winnebago shows your rig having either a 80 or 90 gallon tank depending if it is a Chevy or John Deere chassis respectively. In any case it is not a fun job pulling the tank out.

thank you I believe it is on the chevy chassis I will pass along the info though thanks

yep well our tank is 86.1 gallons and what a job hubby and son pulled it out he heard some where to use cider vinegar I believe a you tube video any way were getting ready to reinstall to see how it goes will let you know how it goes then onto the next task its a fixer but it is coming along 

Just a word of caution!  Many years ago I was able to buy a van at a very low price because the owner had spent a year and Mucho $ trying to correct a stalling problem.  It turned out that someone had used a fairly long piece of fuel hose from the metal fuel pipe to the fuel tank.  Over time,, as the hose deteriorated, it would kink when the fuel pump at the engine created enough suction.  It would shut down the fuel supply until the vacuum dissipated, then, the vehicle could be started and run again for fifteen or twenty minutes, till it happened again.

I have a Class A Winnebago aswell, The previous owner of mine installed a completely new (hose) fuel line (I think the old one rusted away), new filter, and a series of magnet systems that pulls rust out of the fuel. I guess it works cause I have not had any problems with it. not sure if it is a temporary fix or not, I don't know much about it

sorry my engine is such a mess. haven't started with it yet
