98 fuel system
I didnt know where to post this, but is there any difference in the fuel system from 97-98 and 99 and up. I know there is a return line on the 97-98 but does that mean that you can run more peower with that fuel system then the later models.????

Yes, the '97-'98's have higher power potential. There is less pressure drop in the fuel line system between the fuel tank and the injector rails. This is due to the fuel pressure regulator being mounted at the fuel rails rather than back near the fuel tank. '97-'98 Vettes run richer than later models, due to pcm fuel table settings. They use a larger injector, also. Be glad that you don't have a fuel system like the late '03's and '04's. Due to changes because of emissions, it is even worse than the '99-'02's.

Nice color choice, me too. Remember "ALL Corvettes Are RED, the others are just mistakes"! (ACAR)
