if the WIF light is illuminated -it is best practice to drain the appropriate filter or filter bowl. Nuisance WIF light illumination due to wiring condition is a maintenance issue that could hide a catastrophic event until the engine stops.

It really depends on what type sensor system is in play; if a float type like found on early generations of Duramax is illuminated there is a large volume of water present.

On electronic sensor type -it only takes a small droplet of water to close contact of the sensor.

WIF lights are for catastrophic event protection -ignore if you want, but the consequences can be expensive.

All the comments can lead you to minimize the need to pay attention, but anytime you purchase fuel -the risk of water is present and must be managed.

I have been driving diesels since 2001. Never had any water in the fuel. I change the filters when the truck tells me to. They last a long time.

If you ever get a WIF light.... Deal with it immeadiatly! It means you probably gt a lot of water at your last fill up. It is one of those things that hardly ever happens, but when it does, it is a big deal. Kind of like your oil light coming on. People worry about it too much though as it probably will never happen to you.

I have a 2018 Ram 2500, with it you replace both fuel filters every 15k. Go to www.Genosgarage.com for best prices on Oem filters. He does a great job explaining why you should no go with a non-oem filter on a diesel.

I've had a water in fuel light come on once. I pulled over immediately and drained the primary filter. If you get fuel with water in it there is no way of knowing how much water you got .... In the rare instances that a water in fuel light comes on I would recommend pulling over immediately. Draining your filter periodically is a waste of time in my opinion. If there is water in the filter bowl the light should be on. If there is no water in the bowl why are you draining it?

x2. There are some good videos on Youtube on doing it yourself. For S&G I asked at the dealership last time I was in how much to change them. Their quote was close to $300. Last change took less than an hour so I guess my time is worth $200 an hour. Wish my employer felt the same way

Sorry, my post was a tad misleading. Was on vaykay last week. My work has been deemed essential and having been w/ this place for close to 30 years, was pretty safe from getting laid-off. Did drop down to 4 day work week, but still goin'.
