An easier way to prime the fuel and oiling systems

A fast way to prime the engine for both fuel and oil is to loosen all the injection line fittings at the injectors, then remove all the glow plugs..be sure the wires wont ground out on anything. Turn the engine over with the starter...it will turn over faster. When the fuel starts leaking from the lines, tighten them back up. Turn the engine over again. When the fuel starts moving through the injectors, you will see a mist from that cylinder. When there is strong mists from each cylinder, replace the glowplugs and start the engine.

Don’t hold the starter on for more then 15 seconds at a time..let sit about 15 seconds between.
