A few things to build on Larry's comments. Concerning the fuel manifold tubing - replace it and either buy some extra tubing and a plug or save the old as an emergency spare and put it in your glove box.
Check your radiator hoses and replace if they appear aged at all - this is good insurance.
Check the battery tray and keep this area clean and rust free if you plan on owning the car a long time.
Concerning the fuel system, the only thing I would add is that you ought to runb some diesle doctor through the system to make sure youdon't have any fungus growing in the fuel. After you have run a few tanks through, I would then pukk the main tank strainer and replace it. This is cheap insurance too.
Lastly, I am told the hydrulic suspension tends to get ignored alot, so replace the fluid and the screen.
