    My neighbors kid accidentally put gas in the diesel tractor. Its an old Ford Tractor. So he drained all of the gas out, put the diesel in, and it wont fire. Might it need to be primed?

    If so, how do you go about doing that?

    Any ideas?

    crack all the injector lines open at the injectors, turn the motor over, once you start getting diesel up there close them up while its being turned over....works on most older diesels

    mike... do what bowtie said....
    when the fuel starts coming out you will feel the lubricity of the diesel....
    normally the fuel wont have any air bubbles anymore after its bled for 5 or ten seconds....
    this is a common occurence when you run diesel tractors out of fuel... its no big deal

    a little gas wont hurt anything and will burn up anyway.... some truckers used to mix a little gas and other oils into their diesel to raise the cetane rating.... I dont recommend it because it can do harm over the long term to the engine and pump (gas has little lubrication) but one time a little gas should fire right off

    Is there a hand pump near the fuel filter? If so put on a new filter with out any fuel in it and hand pump it. There should be a "slobber" hose that the fuel/air bubbles will drain out of. Just pump it untill the bubbles are gone. Always make sure You use a dry filter otherwise you will just be putting nonfilterd fuel into your injectors.
