For a sanity check, wondering if any of you have gotten your car to pass emissions with return fuel? I brought mine out to CA from Detroit and am hoping this won't be an issue. From a testing perspective, I would expect it to pass.
no smog shop should care about a return fuel system.. It's not illegal to change your fuel system either.. I would think that you'll be fine.. I'd be more worried about an aftermarket midpipe.
it is illegal to modify your fuel system i.e. fuel rail, inj or regulator.
