pressurized lines replacement??
 

Is it okay too use fuel injector line that is rated at 120lbs instead of the line for the porsche which is rated at 50lbs. Also this line seams to have a hard nylon core where the line I'm going to replace it with is all rubber. If I get the exact line form porsche it will cost me 117 where my replacement will cost my 7. I would rather go the cheap route.

the line I'm going to use is fuel injector line.

no one know's any thing about doing this???

sure, don't.

If you have a CIS injection system (likely if you have plastic fuel lines) the peak fuel system pressure can range from 65 to 97 psi depending upon year and model. Also the pressure rating of fuel line depends upon temperature with pressure capability declining with temperature. The main problem may be to get the rubber fuel line to seal to the end fittings required for your injectors and fuel distributor. Your black plastic lines are a grade of nylon with a protective rubber-like sheath. You can replace them with inexpensive replacement nylon fuel line from Mcmaster-Carr but it'll be work.
