Fuel system Help

["deloreanz" <deloreanz@xxxx>]

Im looking at a Delorean for sale and the person has had it garaged 
for years and probably has only started it every now and then. What 
steps would I need to take (if I bought it) to ensure that the fuel 
does not wreck the engine with impurities from sitting a long time? 
Just change the hoses associated with the fuel system? Thank you so 
much for any feedback.
