    On Diesels its been said bearing failure of the HPFP then fuel drips onto the exhaust manifold.

    On petrols fuel line leaking has been said to be the issue.Whether they fail or rub through on something,i don't know.

    D4 up in flames

    Having refuelled running motorbikes whilst sitting on them during enduro races involving nearly always a gush of fuel at the end cascading over the super hot exhaust and (air cooled) cylinder head I have always been impressed how resistant to ignition petrol is without a naked spark or flame.

    Far more scary and likely is a pressurised jet of diesel on something super hot. Usually can only be the exhaust manifold as the water cooling on an engine keeps the block pretty cool.

    As has been mentioned, with diesel direct injection a high pressure diesel leak onto the exhaust / turbo is the cause of most of those fires these days sadly.
