tweaks fueling rule for trucks: NASCAR has tweaked the pit-stop rules for Camping World Truck Series teams as it will force them to use one crewman to fuel the car instead of giving them option of using two crewmen. NASCAR instituted a rule this year that allowed only five crewmen over the wall on a pit stop, and a team can no longer change tires and fuel the car on the same stop. In the past, when teams were allowed to change tires and fuel the car on the same stop with a limit of seven crew members, teams would use five crewmen to change tires, one to fuel the car and one to hold the catch can for fuel overflow. But with the new rule, some teams last week used two crewmen to fuel the car at Daytona International Speedway since they had an extra person available and it takes two gas cans of fuel to fill the tank. When one can was emptied, the first fuel man would move away from the car and the second crewman would be standing by with another gas can to finish the fueling. Tweaking the rule this week, NASCAR will allow only one crewman to fuel the car, so teams will have to go back to the original method of the fuel man handing the empty gas can to a crew member across the pit wall and have the second gas can given to him to finish fueling the car. NASCAR announced the rule change during the prerace drivers meeting Saturday morning at Auto Club Speedway in California.(SceneDaily.com)(2-21-2009)
