Hatterasguy,

I would concentrate on fixing the air bubble problem before touching the IP or injectors. Most of the air will go out the fuel filter bleed hole and back to the tank, but you may have more air entering the fuel system than the bleed hole can handle.

Some place there must be a hole in your fuel line. Try pressurizing the fuel tank slightly (No more than 1 PSI should be applied to the tank or it might expand) and look for leaking fuel along the entire length of the fuel line. Remember there is an expansion outlet in the fuel tank and it must be blocked to pressurize the tank. Also look for leaking fuel around the fuel pump. Eventually you should find fuel dripping on the floor in the location of the leak.
