Where in SC are you located?
There is a guy in Rutherfordton, NC who does pretty well working on stock Z's. I have used him several times and he knows the stock fuel injection pretty well, oh, and he is very cheap.
Maybe you can do like 240hoke did and find a substitute from McMaster Carr or Steele Rubber Products.
His was on a 240z but both companies have one metric crap ton of rubber products.
You can usually find local shops to make your hard lines with whatever fittings you want. I used to use a local one all the time to make hard lines for big truck AC systems, was cheap and faster than ordering from the dealer.
