How do you bleed a diesel fuel system?

Answer 1

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
