Well everybody always says it. Don't run your diesel out of fuel!!! Well I ran

my diesel lot of fuel so I'm gonna go ahead and show everybody what to do if

the air out go ahead and close the bolt to seal it off. Next in line is the high

battery is fully charged go ahead and crank the engine over this is going to

start to build pressure in your fuel system but the engine isn't going to

air out go ahead and close it up and go to the next nut once you get the air out

of there of course go to the third injector and you can really see quite a
