I don't know if there is an increase in car fires but I could understand why. Most multiport injection vehicles have a fuel pressure between 30-50 PSI with a 3/8" supply and 5/16 return line. If the fuel regulatior jambs (more common on ford trucks) the pressure will go above 100 PSI. Over the last 10-15 years manufactures have been switching to vinel/plastic fuel lines for the whole auto. Every joint, injector, & filter has o-rings that is a possable leak. When they leak they pour fuel out. Once a car starts on fire it is almost doomed. They have so many plastics, rubbers, fluids that burn (even washer solvent) it is hard to stop a fire.
