I am just amazed that Newman's car wasn't engulfed in flames. It was burning around the gas nozzle and then gas started gushing from the tank onto the ground. It had to be the grace of God that it didn't explode into flames.
Those racing tanks rarely leak. Many safe guards. Fuel pump stops when motor or stops
Only fuel leaks you’ll see is what is in hose from tank to injectors. Fill line has two check valves. One on side of car, one in tank
I believe that was water running out. Gas would have caught fire.
They carry a tank and radiator
More water helps cool motor in traffic and cooler motor means more horse power
Also have large oil tanks (and no oil pans on motor) for same reason, cooler oil equals cooler motor They hold much more oil than average cars
That might have been oil. They use really thin oil in restrictor plate engines. Also increases hp
