Oldsmobile/Buick Repair: Where can I find detailed information on replacing fuel pump and filter on a Oldsmoblile Delta 88 ?, oldsmobile delta 88, fuel line

Question
I am trying to find detailed information on how to replace the fuel pump and filter on a Oldsmobile Delta 88 year 1987. The car has sat in a field for 4 years and we don't think the pump is good anymore. It will only run for a few seconds if you are spraying it with starter fuild.  

Answer
1987....chances are it has a carburetor rather than fuel injection, so you need to know that first.
if it has a carb, i'd say some Berrymans carb cleaner would be a big help, sprayed into, on, and around the carb, as well as in the fuel line fitting.
