1994 German GP (Jos Verstappen): The most catastrophic fire of the era occurred at Hockenheim. Benetton mechanics removed a safety mesh filter from the Intertechnique fuel rig to increase fuel flow. Fuel sprayed over the hot engine, instantly creating a giant fireball. Verstappen suffered burns to his face.
1995 Belgian GP (Eddie Irvine): Fuel spilled from the nozzle onto Irvine's Jordan-Peugeot car bodywork during a standard stop, triggering an immediate flash fire that engulfed the rear cockpit before being extinguished.
2003 Austrian GP (Michael Schumacher): A damaged internal rubber seal on the Ferrari fuel rig caused fuel to drip directly onto the scorching engine cover. The crew sprayed extinguishing foam over the flames and Schumacher, who calmly waited, stayed in the race, and won.
2008 Singapore GP (Felipe Massa): An automated electronic pit light system mistakenly turned green before the fuel nozzle was detached. Massa drove away, ripping the fuel hose completely out of the rig. Highly flammable fuel leaked along the entire length of the pit lane, though it miraculously did not ignite.
2009 Brazilian GP (Heikki Kovalainen & Kimi Räikkönen): In the final year of refueling, Kovalainen prematurely tore away from his McLaren pit box with the fuel line still locked into his car. As he dragged the hose down the pit lane, fuel sprayed backwards directly onto Räikkönen’s Ferrari, sparking a terrifying flash explosion over Räikkönen's vehicle
You would think by now they could develop an insertion mechanism that slides the refueling hose into the car easier. Looking back at refueling, that seemed to be the main culprit in slow stops--getting the refueling nozzle into the car smoothly to get the fuel flowing. If they can get that worked out, it would be a big improvement in consistency and speed, imo.
F1’s first pressurised refuelling system by cobbling together a large diameter hose and a pair of aluminium beer kegs which were pressurised to 30PSI and could pump 30 gallons (136 litres) of fuel into the car in approximately 3 seconds. It was introduced in 1982 and banned for 1984
F1 next in-race refueling in 1994, utilizing advanced Intertechnique gravity-fed and pressure-assisted fuel rigs sourced from aircraft refueling system. Designed to pump 12 liters of fuel per second and weighed about 250 to 350 kilograms
