Aerostar power steering leak

[Guv Bob]

Hi folks,

I have an 97 Aerostar and noticed a leak around where the high pressure hose connects to the PS pump. The metal tube was loose. I assumed that was the problem and had it replaced at the local mechanic. The new hose is also loose there at the fitting and he tells me that this hose is always loose at that connection there. The nut is tight, but the tube moves around. I've never heard of such a thing on a pressure line. Is he right?

Second question -- it still leaks. If it's supposed to be loose, is it worth trying one of the 'stop leak' fluids before spending the $XXX replacing pummp and/or rack & pinion?

Thanks!
