It's been 15 years since Formula 1 banned in-race refueling and required that each car commencement each Grand Prix pinch enough substance to complete nan full distance. Before nan ban, F1 teams converged connected a azygous royal solution to refuel cars successful seconds: pressurized instrumentality initially conceived for filling nan monolithic tanks connected commercialized airliners. While incredibly efficient, nan rigs occasionally led to fiery incidents successful nan pit lane erstwhile stops went awry.
Brabham introduced modern refueling into F1 during nan 1982 season. It was a strategy conceived by Gordon Murray to find a competitory advantage astatine nan tallness of nan world championship's first turbo era. At nan time, nan 1,279-pound minimum weight regularisation accounted for nan substance and different fluids loaded into nan car. Murray correctly theorized that nan Brabham BT50 could beryllium weighed pinch a afloat tank, past return nan commencement pinch only capable substance to make it to a refueling extremity halfway. The BT50 could walk nan full title astatine a lighter weight and person nan capacity of moving astatine higher boost pressures.
Despite Brabham not winning a azygous title pinch refueling successful 1982, nan clear advantage that refueling created led each front-running squad to adopt nan strategy successful 1983. Brabham was still capable to capitalize connected its accrued acquisition arsenic nan team's Brazilian driver Nelson Piquet won 3 races and nan world championship. However, nan sport's governing assemblage banned refueling and introduced a fixed fuel-tank capacity successful 1984, citing incidents during stops.
F1 drivers could extremity pulling distant pinch nan hose

The astir vulnerable rumor of nan 2nd modern refueling era was a driver pulling retired of nan pit container pinch nan substance hose still attached. Fuel was nan past point that drivers had to hold for, truthful it wasn't uncommon for them to beryllium inadvertently fixed nan greenish ray erstwhile nan different unit members backed distant from nan car.
It happened doubly complete nan 2 anterior seasons. Ferrari's Felipe Massa near excessively soon during nan 2008 Singapore Grand Prix. A twelvemonth later, Heikki Kovalainen did nan aforesaid pinch his McLaren successful Brazil, isolated from nan substance successful nan hose sprayed compatriot Kimi Räikkönen and his Ferrari earlier being ignited by nan basking car. According to Crash.net, Räikkönen vanished nan title but admitted that he was concisely blinded by nan flames.
Pit stops are acold safer today. Tires are nan superior constraint connected pit-stop times successful F1 today. If thing goes wrong, it's typically a lengthy pit extremity because of a instrumentality weapon issue aliases a driver pulls retired of their pit container without a instrumentality attached. While F1 could bring backmost refueling pinch nan gravity-fed systems utilized successful endurance racing and IndyCar, I uncertainty anyone wants to spot sub-three-second pit stops spell away.
F1 went to an aviation instrumentality supplier for refueling rigs
The FIA would reintroduce refueling a decade later successful a much regulated situation to adhd a furniture of strategical intrigue for fans. The teams successful 1994 were provided pinch refueling rigs from Intertechnique, a French aviation instrumentality supplier. According to F1 method expert Craig Scarborough, nan rigs pumped successful substance astatine a complaint of 12 liters per second. For comparison, nan run-of-the-mill state position pump successful nan U.S. has an EPA-mandated maximum of 0.63 liters per second. With specified a precocious travel rate, nan nozzle had an integrated breather to thief vent aerial retired of nan vessel while their gasoline was being pushed in.
Refueling would beryllium banned again successful 2010 owed to costs concerns, information risks and a desire to create much on-track action for fans. In nan aftermath of nan Great Recession, F1 was hopeless to trim costs. In a 2006 TV vignette (seen above), Red Bull Racing explained that it took six group to run nan refueling rig. A refueling prohibition not only eliminated nan costs of nan strategy but besides nan unit needed to run it.
