noob fuel questions, a question about fuel lines etc... Options

[pedalpower]

I searched. Read some interesting threads. Even one about which states experience the most freedom. Alas no direct answers, so...
I just found a 74 2.0 with 49,000 miles and the original owner says I can have it for a small fortune. Needs injectors replaced, and fuel lines replaced.

I searched injectors and three possibilities pop up with three very different prices. The most expensive are the Bosch at 200 a pop, then the bosch at 70 a pop, and then the off brand at 30 a pop. Actually, I bet the injectors in the car are fine but need new rubber, but my gut is telling me that the 200 a pop is going to be the answer.

I will need to replace the fuel lines as well. Any indea as to who makes a fuel line that I'll only have to replace once? Where and how much?

I'll be going through the car over the next few weeks and will have a better idea of whats going on (first hand knowledge) for more detail.

Many thanks!
