I found Andy's T fitting with the fill line. It is in the front of the case just before the return to the radiator. I was wondering since Nealh was mentioning it usually goes before the pump and Andy's pump is in the back of the case. That would be a long fill line, but I see Andy just went before the radiator but is that before the pump? I believe the T filling is after the pump between the radiators.
