Fuel Lines

I am just about to begin swapping a TPI into my RS. Do the fuel lines need to be replaced due to the higher pressure needed to feed the TPI?

Has anyone successfully done this conversion leaving the stock fuel lines in there?

if u've got a 92 RS, then the stock motor should be fuel injected regardless of V6 or V8. therefore your stock fuel lines should be for high-pressure fuel injection. Assuming that u've somehow got a carb'd motor in there, the fuel lines running to and from the tank should still be hard lines anyway.
