While there are all sorts of ways of priming the engine (air pressure in tank, pressurized weed sprayer connected to the primary fuel filter, etc), most people consider an electric fuel pump to be the best option.
There are two ways that electric fuel pumps are "plumbed" into the system. One way is to install the pump in a parallel circuit and control the flow with valves. The second way is to install a "flow through" pump in the supply line from the tank to the primary fuel filter.
The electric pump does not need to be powered except when priming the engine.
I use the parallel system on my bus. That way I can remove the pump and use it for other applications if needed. Whenever the subject comes up, Clifford always advocates the Airtex flow through pumps. I made a mental note (several times

That unit is sized for 5/16 hose. Maybe that is enough flow capacity, but I would prefer something larger like the E8090: http://www.amazon.com/Airtex-E8090-Univ ... B000DN7VLK that has 1/4 inch pipe thread and 3/8 hose fittings.
