New NASCAR refueling system not well liked

NASCAR's change to a self-venting refueling can, which reduced the number of over-the-wall crewmen to six, appears to make the task slower and more difficult.

"The old system, it never slowed down the (fuel) flow when you were plugged in," said Derick Jennings, fueler on A.J. Allmendinger's No. 43 Valvoline Ford. "Another thing that will slow the stops down is that you have to go back to the wall and grab the other can. The catch-can man used to be able to hold that first can while you did that. You will lose 2 1/2 to 3 seconds in between cans when the car isn't being fueled at all."
