Filling up while truck is running
How dangerous is this? I have a friend that does it all the time and it always makes me nervous.
I did this with my diesel, but not sure I would do it with a gas truck. What are your guys thoughts on this?

Why would you leave it running?

Filling the gas tank with the engine running can cause a check engine light on the newer Fords. This causes a trip to the dealer and a possible fee to reset it. The local dealer makes sure to tell you this. They make the point of telling you Ford will not cover this repair/reset under warranty. Labor charge around 1 hour.

It's the possible static electricity generated by the truck's systems being on that is the danger. The exhaust and everything stays hot during fueling. That's why they want us to fill portable gas cans on the ground, static discharge can happen if it's in the bed of the truck, not grounded.

Not as dangerous as it was many years ago because most fuel pumps are internal to the tanks and electrical systems are shielded much better than in lthe past. I wouldn't do it under any circumstance. I been on fire before and never want to experience it again. More so, I don't want to put other families at risk.
Actually, static electricity is more of a risk in the winter with the drier air. Fortunately, though, the fuel vapor is down with the colder air
Below is a quote from another forum, which makes sense IMHO.
'As a firefighter that has been properly trained, I can tell you that the above statement completely is wrong. The intent of shutting off a vehicle while fueling is to eliminate any possible sources of ignition. Gasoline vapor is highly flammable, when in concentrations within its flammable range (not too rich or too lean). Older cars are worse, as the electrical systems are not as isolated as newer cars. The issue is that the vapor that escapes when filling can find a source of ignition and cause a fire. Gas cans need to be placed on the ground and the fuel nozzle needs to be in contact with the can when being filled to discharge any static electricity that builds up during the fueling process. Cars have a "flap" that grounds the fuel nozzle to the car automatically, so no static discharge will occur.'

I noticed my 2011 fuel tank has a true overflow tube - it comes out somewhere under the bed. I had a latched fuel nozzle fail to shut off before, gasoline came through the overflow tube, hit the ground at an impressive pressure, and sprayed all over everything. I waited about 10 minutes before I started the engine, didn't want any problems
I shut the engine off to fuel no matter how cold it is - if it's -30, I'll use the remote starter to start it back up when i go inside to pay. I even go so far as to remove the keys from the ignition if anyone else is in the truck.
