California has the best gas dispensers. It seems they have by law all gas pumps requiring these really nice fume trappers on the nozzle dispensers. Very satisfying and nice to fill up in California as compared to other states like neighboring Nevada which has no fume guard at all.
Hummm filled up today in Somerset Hess took 9.850 gallons without spilling any, I think it was full but I'm not sure. The thing is, it will take 10 gallons exactly if the low fuel light is on and it was not on at all so I have a hard time believing I had an accurate fill up. I did pump it slow and it only auto-shutoff once ... After that I pump about 0.2 gallons at a time then wait for it to flow into the tank. My filler pipe has an anti surge flapper valve as it goes into the tank a few feet below the filler cap and that's what slows the release of the Air and the inlet of gasoline into the tank. Will know when I come down to the full mark if I got the last 2 gallons in this time ... ScanGuage says I used 8.02 gallons since the last fillup. Hummmmm that should be about right.
I guess they only suck in the fumes at a rate equal to the fuel coming out because I got a whiff of the gas going in my tank yesterday and I don't hear any air sucking noise when I am filling the tank.
