1998 GMC Jimmy

Engine Performance problem
1998 GMC Jimmy 6 cyl Two Wheel Drive Automatic 130000 miles

My mechanic says I need a new fuel injection system and that there is an upgrade system, other than the original system that it has. He said he has replace numerous spider injection systems on the Jimmy and the upgrade though expensive isn't that much better, because they both have a very small plastic carbon ( I think that was the wording I'm not sure) hoses, and the upgrade system wasn't improved that much to make a big difference. What is the difference between the 2, and is the difference big enough that it is going to take care of the problem?
The suggestion was to sell my car. I love my car, but I don't have the money to keep replacing the fuel injection system. I was told it probably won't last very long, that it is a poor excuse for a fuel injection system, very problematic. Is this true? I have been going to this mechanic for 15 years?
Please help. Thank you for your time.

What's wrong with the spider-is it the pressure regulator leaking, nut kit or poppet valves problem-

All I want to find out is, if the updated fuel injection system is really better than the original? It doesn't seem to be the best choice, to put any kind of plastic in a part that will be so close to an engine. I know it is suppose to have some type of carbon in it, but plastic doesn't wear as well as some other materials I'm sure that could have used. Then knowing how unstable plastic is, having it (parts) cost so much to replace, with again PLASTIC. It's a 1998 car, and they make a part that is unstable then make that part really expensive. That seems like a really responsible thing to do. I'm sorry if I sound upset because I am. I really love my car, but I can't afford to have this happen. If it happens again I will have to get rid of it, and I don't want to. Believe me if I get another car GMC will not be my 1st choice.
Again I'm sorry, I have to try and find the money to get my car fixed a month before Christmas! I appreciate your response to the difference of the 2 systems. Thank You. Gail
