Fuel Pump in frame rail
I have a 1983 6.9L f-250 with an ATS turbo kit on it. When I bought this truck it had a small fuel pump in the frame rail that was run by a switch in the cab. My guess is whoever installed the turbo and rebuilt the motor also added this. Any ideas why they would have added the pump?

What usually happens is fuel leaks letting air into the system allow the fuel to drain back to the tank making the truck difficult to start after sitting. Adding an electric pump is kind of a Band-Aid to the problem. The electric pump will get the fuel back to the IP almost instantly allowing you to start the truck right away as the factory pump can only move fuel while the motor is being cranked. Dortiz also makes a valid point, the factory pumps are kind of a pain to replace and maybe the PO was lazy. Can you tell what kind of pump it is? The only problem with using an electric pump is that if it pushes to much pressure it can damage the IP. A standard universal type fuel pump is plenty for a stock or lightly modded IDI as they only need around 5psi of pressure.
