Re: Spring info power steering pump
Newer pumps do not use shims and are locked in place not fully seated with loctite. It may have enough pressure as-is. If you do change the pressure setting, measure from the "nut" shoulder to the body and vary shims based on that dimension. There are different length pressure valve bodies. I would not interchange any parts between them.
A .140" restriction is common for a fast ratio box. If yours is close to that it may be OK as-is.
