Fuel Lift Pumps Diesel - Cummins, Duramax, Powerstroke

Electric fuel pumps which were designed for gasoline engines are typically the lowest cost way to do this, and are typically mounted on the frame rail, close to the fuel tank. There are also more expensive, higher-end systems which usually come with filters and a way to suck the air out of fuel. This kind of system is usually very expensive, and sometimes very noisy, but they do bring excellent performance and unmatched reliability to the table.
