    Bleeding fuel system JCB 801.4

    I finally got around to changing the fuel filter on my JCB 801.4 today but bleeding it with the primer leaver seems hopeless and loosening the union on the injectors seems to require cranking the engine over forever and Iím worried it will damage the starter motor, are there any other solutions as she fires but wonít keep running now.
    One other thing when I was cranking the engine to try and bleed the injectors I noticed bubbling from the base of one injector where the fuel had run down.
    thanks michael
