all EFI's have smart valves, its just a fancy word for the fuel pick ups in the tank. they have a micro screen on them to protect the fuel pump from fine dirt particles and that is what can get plugged up. cat recommends brake cleaner to clean them, not carb cleaner. B)
Maybe a stupid question

I`ve been reading about these "smart valve" problems on the Firecats on the Amsnow forum. My question is do all the new EFI sleds have these so I should know what to look for if I have a problem. I have an 03 Zr 8 efi. Thanks
