Corvette Racing has just extinguished its third fire of the year during the fifth IMSA WeatherTech SportsCar Championship round this season.

The most recent immolation happened on pit lane at Circuit of The Americas towards the end of practice on Thursday afternoon. The fire was quickly extinguished, but not without damaging the rear of the No.3 Corvette C7.R.

Putting the Pratt & Miller squad's 2017 season into perspective, the team is operating with a 60-percent chance one of its two C7.Rs will catch fire while on track. According to RACER, the fire at COTA was traced back to a loose connection where the fuel line meets the injector.

"A small leak at a fuel line connection in the No. 3 Corvette resulted in a brief fire that quickly was extinguished," a team representative said. "Corvette Racing expects to return for FP3 tomorrow morning."

The cause of the fire is similar to the fuel line failure in Daytona that flambéd the No.4 C7.R during January's Roar Before the 24 test day. This is the second time the No.3 car has caught fire after a brief refueling-related incident during practice for March's Mobil 1 Twelve Hours of Sebring.
