American Coach: 2002 Fleetwood Revolution water in Fuel

[Darin1960]

New here , already posted in the New member check in . Anyway, just curious if any of you have a revolution and have had the water in fuel light come on during even a small bit of rain? That is what mine is doing, never comes on except when I hit a bit of rain , then after I am out of the rain the light goes back off. I have a theory that it some how senses a bit of moisture on the sensor from the rain . Sounds crazy but I am confident my fuel is ok being I do drain the filter quite often and as I said only when I hit even a small amount if rain.

Different MH, same issue, happened to us 2 yrs ago when we were travelling thru Montana and BC. Water in Fuel light came on after a couple of days of rain. I drained a little fuel out of the separator bowl, no water. Would be off after startup for 15 min to 1 hr, then light would come on. Some days, no rain but light on still. I called a tech while in Canada and he said drive on. So that's what we did. No more light.

I would check the connector that plugs into the fuel/water filter. Connector should be water tight. I would unplug connector, clean it, maybe put a dab of grease on the rubber seal on connector to help seal it up.

Had to same problem water was getting inside the connector

Good , idea about the grease.

You can pick up a small tube of diaelectric grease made for this purpose at any auto parts store.

Almost surely a loose or corroded connect or the sensor at the fuel filter/separator. If wetness gets in, it closes the circuit and the light comes on, even though there is no water actually in the fuel. Usually just removing and reinserting the wire harness plug to the filter will fix it, though maybe have to do it 3-4 times if its not obviously loose. Some wire grease on the fitting can't hurt either. More than likley, though, it's just a disconnected or poorly connected plug-in.
