How can it be dirty or clogged? isn't it just fuel or water? i dont understand how it can be blocked... Then again i am not sure how the thing works anyway.

 

Wait, I was just about to go to sleep and thought of something. How level does the truck need to be to have fuel drain out? Like i mentioned earlier checking my oil, my driveway is a on a slight incline, with a bit of a nose up angle to it. Can it be the angle? or does that not matter at all and it should have drained out anyway?

 

should have drained anyway. If there ain't fuel above that drain at all times, you're in deep doo doo . . . and your truck isn't going to run.

 

My next thing i was going to say was, I did not start the truck all day before i opened it up. But now i guess according to your post that does not make a difference. I am wondering what and be blocking it for nothing to come out? seems really strange..

 

Each motor will read a little differently on the stick. My opinion.

As for the fuel/water separator a steady stream cap on or off. I leave mine on.

You will have to either pull the filter and look inside for debris or take the cover off and clean it.

I am attaching a pic of it. You can see the bolts to remove the cover.

I wonder if there is anyway that you could've come across an F450 with the 'Ambulance Package'? The reason I ask this is that our newest Fords(2 F450s and 1 F550) with the 6.4s still regen in park. My F450 has had many flashes due to the PCM being replaced twice and a TCM being replaced. As a matter of fact it was just reflashed two weeks ago after a 'shut down' when the tech could not get the codes to clear. Ended up being 2 problems (1 EGT sensor and 1 fan clutch malfunction). After all I have read on these forums, I thought that a reflash would've stopped the units form doing a regen in park, but they still do. Just a thought.

 

I don't know about ambulances. It stands to reason that they may be allowed to regen in park. given their usage. However, my F-350 does not regen unless it's in drive.

 

I wonder if there are different flashes for vehicles that have the 'Ambulance Package'? That is what I meant by my other post. When the computer is hooked to the OBD port and it reads the VIN, does it realize that it is a special use vehicle? I will have to ask my tech and see if he knows. Like I said, the ambulance and rescues still regen in park, but my F350 doesn't. Wondering if there are different parameters that are loaded to different vehicles due to the VIN?

 

Thanks, I actually saw you post that same thing in another thread. I am going to try to find level ground and try draining it. if noting comes out, then i will take off the cover. All i do is take off those 5 torx looking screws? thats it? I wont be covered in fuel will i?

 

some but not too much fuel.

 

Thanks for your help! I will let you know what happens. Its been pouring outside all day, so when this rain stops, I will get underneath it.

 

I to have this loud ringing whine in my truck when I get it up to 1800- 2000 rpm and I noticed the comment on the Fuel Cooling pump in your post- Did not know about this pump and it seems the dealer does not either.
How doe it get air in the system and still work. Does anyone know

Here is my post
I recently purchased a 2008 F250 super-duty with the 6.4 L PS diesel with 59,000 km on the truck, The turbo and exhaust sounded funny about a week after purchased the truck with a ringing whine in the turbo I think and/or exhaust (Intermittent). I had purchased the premium extended warrant (phew!) and the dealer said it needed two new turbos. So they changed them both ( plus ceased front brake calibers) plus a few other items $$$ still
I still have the ringing whine in the exhaust which as a very high pitched ring whine that resonates in the exahust at about 1800 RPM and is VERY loud but intermitte, The dealer heard the sound once or twice and it's loud it but does not know what it is or how to fix it and said just drive it until it get much more frequent until they can figure out where it is coming from
Has anyone else had this problem??
ERG valve -waste gate shutter- I have no idea??

If it is the Fuel cooling pump please let me know and my truck is due in the shop in a week for another issue and I will ask them to check this pump. If it is I will let you know.

Have you noticed that it only does it at a certain temp?

 

Sorry for the delyed response
Originally the noise only occurred when the truck was up to full operating temp and I took it in to the dealer. As mentioned the dealer changed both turbos under warranty and I got it back and the same thing, but this time it was occurred a few times right from the get go. I took it back to the dealer as mentioned they said drive it until it get more frequent and they can find out where it is. Go out of the dealer parking lot, drove to the curb and hit the throttle and wow what a whining/ringing noise. Only did it twice on the way home about 30 miles.
