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 got there first

Here is a good explanation and picture of the bladder: > http://www.autoshop101.com/forms/Hybrid13.pdf Well, I am not going to do this in the Prius now (not that I did, but I have done so in the 98 Sienna just so I run out later rather than sooner)... 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.... Tomes

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. Tomes

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. Tomes |
