Ran out of diesel..How do i restart?

I drove commercial trucks for over 40 years and over 2.5 million miles. Have primed cats with pump however with newer electronic engines they are not usually on there. Salesmen like to tell newbies to dump out filters because of water, not usually necessary. If you do take filter off to check for water just look into filter with a flash light and you will see puddle of water in the bottom if any. If water change filter, fill new filter with fuel, then spin on. Fuel filter should be good from service to service. As said any time filter changed always fill with fuel before replacing. most fuel stops these days are pumping enough diesel that you won't get water after going thru there filters. Also when storing motorhomes, gas or diesel leave fuel tank full to prevent condensation build up in tank. Good luck.
