Fuel System Contamination

["deloreanz" <deloreanz@xxxx>]

Thanks for all the help in the past. Is there any proceedure i can 
follow to check how far the fuel contamination has gotten(like if it 
got past the accumulator/distributor up to the injectors? I'm 
considering just replacing the fuel pump/accumulator/filter just to 
be safe, is that absolutely nessesary or could I check if any of 
those are still good? Also how could i check the distributor for rust
(hence injector contamination)? Thanks again,
