I changed out a bad power steering pump but the seal on the high pressure fitting would not seal up on the new pump. So, I got a new fitting but it is not great. I have the car on jack stands and with the engine on there is no leak, but when I turn the wheel to the extreme stops, a fine stream of power steering fluid shoots out from the fitting. I am using this 5/8-18 to 6AN fitting with a teflon seal (https://www.summitracing.com/parts/DSR-090210LDS). If I tighten more I am concerned I will deform the teflon seal. Any advice on how tight this should be? If I lessen it then it leaks while under power.
Stock ford power steering pump with the plastic reservoir and 5/8-18 port (not the metric port version used later). Any other advice on perhaps a different fitting or seal?
