You paid WHAT for a new PS pressure line? Sounds like you've been having the stealership do all of your work, and that will always drain money like no other. If you want to save money, or at least not pour money into it then do your own work, or at least buy your own parts and supply them. Sites like www.rockauto.com offer up OEM parts for way cheaper than the stealership, or comparable aftermarket parts.
Trust me when I say the stealership will rip you off every time you turn around. They tried to quote me $300 on a battery ground cable once.
