    I have a Fiat X1/9 that is exhibiting a weird problem.  Every now and
then the engine will die.  When this happens, there is no fuel in the
fuel filter in line from the pump to the carb.  After sitting for a
while (sometimes a few minutes, other times several hours), it runs
fine.  Once when it had failed, I disconnected the fuel line and cranked
the engine and the pump didn't output any fuel.  I sucked on the output
from the pump and was able to easily get some gas out, so the lines are
not clogged.  Blowing back into the line I could not force the fuel
backwards, so the valves in the pump were ok and it didn't have a leak.
Although I am not absolutely sure, it seems to happen only when the
engine is rather hot (long trips on hot days), so perhaps it runs after
it has cooled down?
    Do these symptoms make sense to anyone out there?  I have not run
pressure and capacity tests on the pump, but I intend to as soon as I
get a chance.
