That one is not a likely suspect for air ingress. Air ingress more likely from:
1. Anywhere along the fuel supply line, esp. extra extra (smaller inner) flat o-ring on the fuel filter seat.
2. Bad IP mainshaft seal.
3. Fuel return lines. Could be downstream of the IP fuel OUT, or even the small fuel spill tubes from the injectors.
