The fuel injected VW's have much higher fuel pressure than the carbourated
ones.  I can only speak from VW van experience, but from this standpoint all
fuel injected busses (that is, 1975 on) are at risk.  Even the smallest
pinhole in a fuel line will cause it to "piss" fuel all over the engine
compartment in a steady, high-pressure stream, while a similar pinhole in a
carbourated bus fuel line is more likely to seep than to shoot fuel.
Therefore, the former is more likely to spray fuel onto a source of
ignition.  On the other hand, using old, dryrotted fuel line on any bus (or
car) is certainly a fire hazard.
