If they all gave out then you most likely got a seal break in the lines. That actually could be a simple fix of finding what hose broke off or seal broke and then reattach or replace.

My Dad and I use Andy's Muffler and Auto repair on his Lincoln and my Firebird.  He usually has an old classic he is working on sitting in his back parking lot.  He is right there on HWY 124 just past Oak on the right hand side going up to Lawrenceville (2178 Scenic Hwy N Snellville, GA 30078, (770) 972-8222).  There is also an upholstery shop that just moved in next door.  I am thinking about trying the place to recover my Firebird seats.
