I went through "some" mud and water. Really it was insane amounts of water, like 2 to 2.5' deep, spinning mud and water everywhere. It was more fun than smart.

The water in fuel light came on. I stopped, drained the fuel filter can. The light turned off, came back on a little dim, then went away. Will a wet air filter make the water light come on? I have the 6637 Donaldson.

How bad is water splashing on the air filter? I am not going to do this again, too stressful. 'but did I just take years off my injectors?

 

The water on the air filter won't cause the WIF light to come on. Maybe water was already in the fuel and just made it way up there. Either way drain the filter again and you should get a new air filter just for good measure.

 

X2 You probly had the water to start with. One time the water in fuel light came on in my truck but only when I turned (I think it was right), driving stright it was fine. Drianed the water and no problem. So doing all that bouncing probly made it come on then.

 

Is it possible for a lot of water to splash up there possibley creating a short misleading the sensor to read as water in fuel when its just water in the plug to the sensor?? Just a thought, I am sure that it is far fetched, but it was a thought anyhow...LOL

 

Good point, I was kinda' thinking that about the sensor wires or the plug as well. This motor has never seen such harsh conditions.
I remember saying "you only live once" before we went mudding, now I'm seeing how expensive this offroad habit might prove to be.

I dumped the filter can again just for good measures. What is the fuel filter part# if I were to buy from fleetfilter.com? I'm a bit confused about if the new body 7.3 powerstrokes have the same filter.

 

From fleet filter the fuel filter is a 33517 and the air filter is a 56637

 

thanks,
so the fuel filter is different for the newer 7.3ls.
I think you meant 46637 for the 6637 air filter.

 

It is possible for water to splash up that far but it shouldn't short anything out. I have been in mud wher it flows over the hood and mud stains on the bottom of hood and all over motor and nothing happened. That is except for the fact that you permanently stain the turbo housing mud color and you will be cleaning that mud out of everywhere for quite awhile. These trucks will run when most others fail but you must keep the intake air clean and water free. That is why I like my AFE intake box around the filter.

 

Yes on both accounts! thanks!
