But your paranoia level is WAY over the top, if you believe cell
phones can make gasoline blow up. WAY over.
The things that come to those that wait are the things left by those who

How does not topping off at the pump increase the price of the gas?

Well, I am not going to do this in the Prius now (not that I did, but I

From Ray's article:
"Trying to force additional fuel into the tank pushes excess fuel into the
EVAP system. This may cause an EVAP DTC and may even require the
replacement of some EVAP system components"
These things are just getting too complicated now....

I live in NJ too. This ought to be stated that Pump attendants are not
supposed to do these things. I have seen every one of these things done
at stations in NJ: topping off, gassing when the car is on, and gassing
when the driver is on the phone. It is so reassuring that we have these
highly trained technologists working this dangerous job for us.
Now I take my tongue back out of my cheek and state that I would not want
to trade in this practice at all. It is extremely convenient that I do
not need to get out and do it, especially when it is bad outside. I also
do not buy the counter argument that having up pump it ourselves will save
us on gas prices. A couple of cents does not matter much now at these
prices anyway, and NJ gas is among the cheapest in the nation due to a
relatively low gas tax rate. This is one of the reasons that I like
living in NJ.

Scott - I saw a surveillance video at work a couple of years ago in Safety
training where someone standing next to their car turned on their phone
and the fumes lit up. That person was standing out at the pump nozzle
pumping IIRC. Apparently there can be a slight spark or its
electromagnetic field can byproduct an arc or somesuch. Not really sure,
but it convinced me well enough.
