I just got off vacation and there was a letter in my mail box from Fleetwood Enterprises. It stated that owners of certain 1997 to 2000 model year gasoline equipped Fleetwood motor homes of some important maintenance requirements regarding the rubber "generator fuel hoses" that were originally installed on your motor home. The letter goes on to say that these hoses were being deteriorated by fuel "formula changes" by petroleum companies (adding additives to gasoline) which is deteriorating there rubber fuel hoses causing them to become brittle which would cause them to seep gasoline and allow air to enter the fuel line. If you have any questions call Fleetwood toll free 1-800-322-8216. I don't own my Fleetwood coach any longer but I thought it was gracious of Fleetwood to send out the advisory letter. So I'm passing this along to anyone on RV. Net that might of purchased a 1997 - 2000 Fleetwood used and may of not known of this advisory. John
Tiffin has similar problem. My parents 04 has a fuel vent hose that has totally disinigrated. Unfortunately, this hose was "engineered" to never be replaced. Workhorse says its a Tiffin problem. Tiffin says not under warranty - although it is part of the emissions system which should be covered under warranty (by law). It is a two fold design issue - first that the hose failed prematurely and secondly that the hose was installed in a way that it is impossible to replace without major work. I don't think they've gone the second round with Tiffin, so I don't know where that stands.
I think you can expect more such notices about deteriorating fuel system components, as use of ethanol expands in the gasoline distribution channels. All alcohols are more corrosive than traditional fuel components, and the life, in this chemical environment, of some of the materials used, is not yet known.
Some chemicals used as fuel system cleaners can also be culprits, but ethanol is the chemical coming at us in high volume.

Why would a fuel hose to a generator be part of an emission system? The generators aren't coverd by emission requirements. I don't think even the main fuel line to the engine is part of an emission system, or at least it's not covered here.

Ethanol has been used for many years here in WA and before that ARCO was 10% Ethanol and we've never had a problem with anything deteriorating.
Yup, Says it right on the pump, "Some of the******we put in our gas now is likely to deteriorate certain components of the vehicles is supposed to be used in"

In this case, it is a vent tube to the gas tank, not the fuel line to generator. Brought it up because it is a similar issue of hose deterioration related to fuel. Even so, the fuel system in any vehicle is supposed to be sealed, no matter what it goes to. Even if your gas cap leaks, your check engine light will turn on and you will flunk emissions. Any vapor leak should be covered.
