Powerstroke Water in Diesel?

bucky7680 · Mar 2, 2007

I have a 95 7.3 powerstroke. The "water in fuel" light came on earlier this week. I opened the drain below the fuel filter for approx 30 sec. Then I replaced the filter After doing this the light went out. The last few days the light would come on intermitently either full brightness or sometimes dimly. The light will go out even if I haven't opened the drain. I have opened the drain 4 times this week. My quention is do I realy have water in the fuel. a bad connection, or a bad detector? I've been buying from the same source for a long time with out a problem. They sell a hell of a lot of diesel because it is the lowest price in town. Is there an aditive I can put into the fuel to remove any water like you can for gasoline?

i have one of those tall skinny olive jars, when ever i drain, my separators, i drain the jar full first. let it sit a while, the water will be on the bottom and fuel on top. this way you can see if just how bad things are. diesel is bad about water. the station is suppose to check their tanks everyday for water. they put comet cleaner on the dip stick, when they pull the stick you can tell how much water is in the tank. you may have filled up when the station tank was low.

I got some watery fuel one time and it took about 3 filter changes to get rid of.

Thanks this sounds like it will be a long process. Filters are expensive but I guess they are cheaper than fuel pump or injector trouble. How about some sort of aditive to speed up the process?

Do I need to drain my tanks?

Have you checked the fuel your draining out to see if it actually has water in it?

It's possible that it's a faulty sensor.

I haven't had time yet. I need to put down an oil drip pan. I can't get any thing up inito the engine space to collet from a steady stream.
They told me that when I got older I would have problems having a steady stream.
