Once upon a time, we used to flow fuel, as they say in boat-testing parlance. That meant disconnecting supply and return fuel lines, splicing in fuel-flow meters, and then running electrical cables from the meters to a computer that would precisely calculate fuel burn. Only one time did I make a bad connection on a hookup and allow air to enter the supply line of an engine—a mistake that promptly airlocked the engine and summarily shut it down.
The steps I took to get things going again are fairly universal. This procedure can vary from engine to engine, so consult your operator’s manual for the correct steps to follow. But generally speaking, this is the idea.
Second, begin working the lever (plunger, whatever) on the fuel lift pump (an engine-mounted component downstream of the primary fuel filter) until bubbles stop forming under the bleed screw and solid fuel comes out. Use rags to keep things neat, and then tighten the bleed screw back up. Do the second secondary if necessary. more
First, back off the bleed screw on top of the secondary fuel filter—three or four turns is usually enough. Some engines have two secondary filters.
And third, repeat the bleeding process via the bleed screw on the injector pump (unless it has self-purge capability) and then again (depending on your manufacturer’s recommendations) on each individual injector. more
By bleeding trapped air from the fuel system, you can restore the flow of fuel and get your marine diesel engine running again. This skill is crucial for anyone who intends to be on the water for any considerable length of time. The steps involved are straightforward and applicable to the vast majority of engines, though it is wise to check your owner’s manual for any procedures specific to your model.
Knowing how to prime a diesel engine involves finding the fuel pump lever or plunger. Your fuel lift pump will be mounted on the engine and connected to the primary fuel filter. Begin pumping the lever or plunger while keeping an eye on the bleed screw. You will see bubbles form as air leaves the system. [links]
Before you can get the air out of the system, you have to know how it got in. Diesel engines should never run dry, as this is guaranteed to cause airlock. Outside of this scenario, air intrusions typically occur when the fuel filter is changed. This can be prevented by filling the new filter with fuel and topping it off as it is absorbed, then applying fuel to the inside of the gasket before installation.
