Good Morning All. Ive replaced the entire Power Steering System on a 1963 1/2 Ford Galaxie 390. New Pump, Power Valve (2X), and Power Cylinder, pressure lines, basically everything except the reservior. The issue is that under prolonged driving power steering fluid leaks out of the reservior from the factory hole underneath the wingnut valley. Spring seems good in reservior and I have rubber washered both sides of the hole. Im confused.
