81 ZXT

I bought my first Z last Thursday. 1981 280 ZX Turbo (blue with silver hood). Aired up the tires, comalonged it onto a trailer and hauled it home. By the time I got it home, 3 of the tires were flat again. I was told by the PO that it needed a fuel pressure regulator and rack and pinion. Put new battery in next day and when I tried to start # 2 injector hose leaked. It looks like the hose is factory made onto the injector. Can that be cut off of the injector and replaced or do I have to buy a new one? I have a little work to do on the car but it will be fun and even more fun to drive. I had a buddy that had a new 82zx and a new 84 300zx so I know they are fun to drive. Of course, that was almost 30 years ago. I'm planning on keeping it stock and look forward to enjoying this site. I will post pics if the ice storm will let up.
