I have electric "priming" pumps on everything and also the factory mechanical pump. Some air cleaners are difficult to remove or full of oil waiting to be spilled so I flip the electric pump on till it changes sound when the needle hits the seat, turn pump off, choke if cold, pump twice and hit starter. Fires in no more than three revolutions. Really nice on equipment like fork lift, riding mower, air compressor with Wisconsin V4, and cars/trucks that are used sporadically. My John Deere diesel powered sand blasting compressor has an electric pump to push fuel to the injector pump which may have been installed by the previous owner. The best electric pumps I have found are the ones used on LUV pickups and the worst are ebay bargain pumps.
