Is there any reason why I should not leave the 6.0 running while fueling? I've always felt there was no reason to start and stop the engine for just a couple minutes for refuling; however, I have noticed a couple of times after refuling my fuel gauge would be pegged down below empty and my "Low Fuel" display would come on and turning off the engine and restarting was the only thing to make the gauge and display go back to normal. Now the other day my check engine light came on also and has not gone off. I have an appointment to take it to the dealer but I was just wondering if it could be related to the fueling issue and if fueling while running was a bad practice with any adverse consequences.

 

The computer can dampen the fuel gauge reading to account for fuel sloshing around in the tank. Think of what happens while four-wheeling up/down some mountain trail. The vehicle will encounter all manner of side to side & front to back changes, but the fuel gauge will show the "level" fuel level for quite some time.

Shutting the vehicle off & restarting it will speed up the process at which the correct fuel level is accepted & displayed.

 

yes to sum it up the sender is not "fast" so that way it does not move ever time the fuel changes angles in tank.

 

I fuel my truck up with it running a lot of the time. Especially in the winter. I haven't had any issues with the fuel gauge in my 07, it always reads right when I get back in the truck. I wonder if Ford changed something so it now recognizes when you are fueling up, and not driving around in hilly conditions.

I would not recommend fueling up with a gasoline engine running though. Gasoline is a much more volatile fuel.

 

I never shut mine down either. Had an '03
that would take as long as 30 minutes to read full.Never had a check engen light come on though. Asked dealer about it and they said it was normal but did not recomend fueling while running.(oh well)
Have an '06 now and can watch the gauge climb as it is taking fuel.

I dont ever shut mine down.. Even when they come out and tell me to.. I just tell em to take their rears back in and read up about Electrostatic Shock and the burning compounds of Diesel fuel.. I still don't get how these attendants seem to think Diesel Fuel explodes like Gasoline.. Morons.. We use to light diesel to burn turd pits in Iraq, I still have my eyebrows LOL..

 

Yeah, a lot of people don't understand how much harder diesel fuel is to ignite. You have to almost try to start it on fire, as opposed to gasoline.

 

Yep.. Thats what I love bout Diesel.. You can literally soak one end of a piece of cardboard with diesel.. Take a lighter and light it.. It just burns.. Do that with gasoline and you'll have no upper body hair LOL

 

Well because when your pumping the diesel the guy next to you is pumping gasoline and you become the problem because you feel your safe because your pumping diesel and never think about whats around you. Nice real nice.....

 

No it's because this crap about Gasoline igniting while running your vehicle is hog wash.. I was a Firefighter back in 1998-2002.. The 4 years I was on the Department, I never once responded to a Fuel Fire at a gas station caused by "Static".. You have a higher chance of walking across the street and getting killed then a pump igniting itself from static electricity..

I'll continue to fuel my truck with it running

 

"Well because when your pumping the diesel the guy next to you is pumping gasoline and you become the problem because you feel your safe because your pumping diesel and never think about whats around you. Nice real nice....."

...and what's this problem? This IS a diesel we're talking about. Remember, in a diesel there is NO SPARK! I'd worry about a guy talking on his dang cell phone before I'd worry about a diesel running next to me while I'm fueling up my Lincoln! (Except for the smell!!)

 

Mythbusters busted the cell phone myth.

 

They sure did A lot of that is myth.. It's like now, my line of work is Network Engineering.. I work with $80,000 servers day to day.. Theory has it that electro static discharge can cause circuitry to disintegrate. I’ve never once been able to discharge enough static to damage a circuit board, even trying. Don’t get me wrong, electro static can produce enough current to cause a fire, blow a circuit, etc.. But the odds of your body being able to generate that much is very very rare.<o></o>

 

They covered this on Mythbusters a while back. They could't get anything to blow the gas up. I run my truck at every re-fuel and love it. In this hot summer weather it is sooo niced to hop into an ice cold truck after a fresh sip of go juice.

 

Just because a circuit board or electronic device still works does not mean that there was not damage.

I have had training that showed integrated circuits with electrostatic damage even though the circuit worked right most or all of the time. These were images made with a microscope showing the internal traces within the IC. The damage can be progressive ultimately leading to total failure or intermittant failures depending upon exactly what is damaged if anything.

Cell phone stuff is mostly urban legend although there is slight possibility if the battery were to arc; but no known actual cases.

There have been documented cases of gasoline igniting from person getting back in their vehicle and then exiting again and ignition when they grab pump handle. Documented cases of filling portable gasoline containers while in pickup beds with drop in bed liners too. Even a few cases of RV refrigerators running on propane igniting gasoline at fuel stations (most of us do not turn the fridge off while fueling our vehicles).

Then again if it is so dangerous for a gasoline engine then what about all the other people coming and going while others are fueling their vehicles. How about the brushes sparking in the starter or the solenoid when they restart their vehicle. Surely the hybrid cars are too dangerous too!
