I always vent because I want to get an accurate measurement of my miles per gallon. The pumps around here will automatically shut off for me with no spillage, but I always recommend keeping an eye on it because the diesel fuel can foam up, especially with no venting. Please keep in mind I am talking about the small fuel nozzles at the local gas stations, and all bets are off if you are using the large nozzles the truckers use.imsos04 said:Out of curiosity, how many people don't vent when refueling? Also, if I wanted to fill the tank, could I just let it pump 'till it shuts off or is there a possibility of spillage?
I've never had it happen in a NB either. Have in a truck though. Preventing this is one of the reasons for the air space that we are defeating when we vent.maxforce said:I vent all summer, living here in VA. I Have never heard of a 1st hand experiance of fuel expanding and leaking out of a diesel....
do gas beetles have this, too?vee_dubya_diesel said:in the filler neck or "pipe" that you pump the fuel into, there is a small black button that when pressed down vents air into the filler neck, allowing more fuel to go into the tank/filler neck.
Diesel bubbles up. push the button, vent off the bubbles, add more fuel, drive farther between fill-ups!
