The Vetus marine diesels come with an electric fuel pump between the primary & secondary filters. I'm sold on the electric pumps.
Priming the fuel lines is never required. I can change my fuel filters, install new dry ones, then just let the pump run for about 20 seconds and the engine fires right up.
The Vetus pumps are made by Facet; It's much cheaper ordering direct from them. They make something suitable for most diesel engines.
