Yes, the F2 uses the same input fitting as the F1 so it can use the same IGL as the one the sell for the F1. The IGL is a very close fit to the lower solenoid though so it can be a bit tricky to install. They recommend keeping downward pressure on the IGL to avoid contact with the solenoid while threading it in. Or, remove the solenoids before installing the IGL and then reinstalling the solenoids afterwards.
