On lap 149, Al Unser, Jr. precipitated a caution period after spinning down the back-stretch and crashing in turn 3. During the caution, Jeff Simmons left the pit area with the fuel hose nozzle still attached. The hose tore, and Simmons's car dropped the nozzle out on the track in turn 3. On lap 150, the leaders pitted. Sam Hornish, Jr. started to pull out of his pits with the hose still attached. The hose ripped, but Hornish stopped in the pits allowing the crew to disengage the nozzle. Team owner Roger Penske accepted responsibility for the error, having told Hornish to go before the fueling was complete. Fuel spilled in the pit stall, but Hornish was able to return to the track and stay on the lead lap.
