If you aren't sure it's the fuel pump, it could be a number of things--tank screen, fuel filters, carburetors, ignition, engine wear, etc. A car sitting that long will probably have problems in the fuel system, anyway.
If the owner just "thinks" it's the fuel pump, I would suspect in the least, the carbs need rebuilding. Does the engine even turn over? If it does, pull the supply fuel line at the carb, turn it over and see if fuel comes out. Make sure there is fuel in the tank and oil in the sump. Are the plugs getting spark? Check the health of the plugs while you have them out. Try some starting fluid to at least see if it will fire.
You could do a compression test to determine the health of the engine. If you can get it running, I wouldn't run it long without changing the oil.
Buying a non-running car is a gamble. It requires a good discount on price.
