I'm not a mechanic but I have ran out of fuel and had an open system for repairs many times. If there is a pump present somewhere on the fuel system. start with that. There may be a need to vent from a valve in the line to help prime, Just study the lines and where they are going. If all this falls just get in and try to start the vehicle. The things to keep in mind are the fuel pump; has to fill the filter again and purge air(this takes time). Also the starter; should be respected enough to give it a break now and again. Bad starter = $80.00. It will seem to take for ever, try depressing the accelarator after you feel the fuel bowls are full. She may chug and buck but she'll clear her throat and exentually smooth out.

ya some diesil engines have a bleeder in the fuel system yup outta dat if bleeding is needed from changing fuel filter, make sure you fill new filter with diesel before installing filter, this will help in removing air. if you dont have can of diesel, use engine oil , it will not hurt engine and will burn off pretty quick when engine is started generally the easiest way to bleed a diesil fuel system is to crack open the fuel line to the number one injector. crank engine , allowing air and fuel to escape from loosened fuel line. once sufficient air has been bled from system, the engine will start. if there is still air in system the engine will run fuff. at this time you should be able to retighten fuel line. while engine is running it will burn off any air left in system. you will know when air is gone as engine will run smooth if you have a glass fuel bowl in fuel system sometimes there is a manuel pump on the bottom of bowl. you can use this to prime the bowl if empty. usually if you have this, you will not have to bleed system most newer diesels do not need bleeding , but will start after a little cranking
you dont have to it does it itself
you dont If you've had a fuel pipe off and diesel has flowed back down the pipe away from the fuel filter, pump the rubber bulb at the side of the air filter until you can hear fuel squelching in it. The engine should start at that point.
A diesel engine uses a high pressure fuel system,which means that it can't have air in it,it's kinda like the hydraulic brake system,if their is air in it,it won't work right. when you run a diesel out of fuel,it sucks in a bunch of air,which must be bled out of the system,in order for it to re-prime its self. if you don't get the air out,then,the diesel fuel will only travel up so far into the fuel line,until it is stopped by air,that's why a diesel is so hard to start after you run them outta fuel.
