Thanks for the reply,
I guess what I meant to ask was do I have to bleed the air out of the fuel system.............
Only if the air in the Racor increased to the point where air would be taken into the fuel line to the engine. This point is beneath the filter canister. Certainly, you can fill the Racor with diesel and run your engine at the dock for sufficient time to see if it stops due to the air and importantly to see if air is still entering the filter or, not to risk the hassle of a longer job, go ahead and pump the manual fuel pump lever with the bleed screw slightly open and see if you have air bubbles. However, if your fuel level in the Racor is still above the fuel effluent line, you should have no air in the system. Take care and joy, Aythya crew
