Good afternoon,

If there air in the fuel line then it could be coming from the fuel pump in the tank. If the pick up hose or line has a hole in it, it will draw air instead of fuel.

Try filling the tank with fuel and see if it still has air in it.

There is also a high pressure pump along the fuel rail. If there is a hole in the line between the tank and the pump, it will show air in the line.

I pulled in tank pump no holes or leaks. Fuel lines and o-rings look okay. Tank was full when it happened. Check valve in fuel reservoir is disassembled.
