I read recently that in NEW ZEALAND there had been a lot of car fires to
classic cars, where plastic fuel lines had melted with the additives in
the leadfree fuel there. The chemical simply diluted the pipe into the
fuel till the pipe ruptured, and fuel ran onto hot manifolds.
Anyone down on OZ know any more?
ALL my three MG's have hardend steel inserts in the exhaust valve seats,
to cope with leadfree, one has an XPAG engine, the other a 'B' series,
the last an 'A' series.
