Steering Pump Pressure Fitting Size?

Does anyone know what size the pressure line fitting is on the back of the power steering pump?

I'm converting my power steering away from the factory crimped rubber style hose and already have the fittings for the gear. At the steering gear, the pressure side is an M18x1.5 and the return fitting is an M16x1.5

All I need is the correct fitting to go in the back of the pump. It looks rather small. I'd venture to say M14x1.5. Or is it 16 also?

Can anyone confirm?

Re: Steering Pump Pressure Fitting Size?

For anyone wondering, the fitting size on the back of the steering pump ended up being M16x1.5


So for anyone looking to do this conversion:

M18x1.5 - Steering gear pressure port.
M16x1.5 - Steering gear return port
M16x1.5 - Steering pump pressure line fitting
