Eric,

You want to use the pump to fill the bowl on the Racor. You will also be pushing some air up the fuel system, through the fuel lift pump to the inlet of the high pressure fuel pump.

• Pump the Racor until you feel the system is full (it will get hard to pump). Once you get to that point,
• crack open the bleed screw on the top of the 2 micron filter located between the fuel lift pump and high pressure fuel pump on the stbd side. Note this is cracked open, NOT wide open because you only want to concentrate on air escaping, and minimize fuel escaping.
• put a rag under the bleed screw to catch fuel.
• Pump the Racor with one hand and you'll see air/fuel being pushed out of the bleed screw.
• Once the air is gone (no bubbles or hissing (solid fuel), close the bleed screw while pushing the plunger down on the Racor pump.
• crack open the bleed screw on the inlet fitting to the high pressure fuel pump (that's on the stbd side front of engine). Again, only cracked open, NOT wide open.
• put a rag under the bleed screw to catch fuel.
• Pump the Racor with one hand and you'll see air/fuel being pushed out of the bleed screw.
• Once the air is gone (no bubbles or hissing (solid fuel), close the bleed screw while pushing the plunger down on the Racor pump.

That should suffice on bleeding the system. You can actually bleed all the way to the injector inlet, but this probably isn't necessary. Start up the engine per normal procedure and call it done!
