Don't know. Just wondering why you would put a V8 fuel pump on a (supposedly stock?) V6.
I don't think there would be any advantage unless the engine/ECU is modified (injectors, fuel regulator, cam etc.) to accept the extra flow/pressure.
While I haven't seen it done, I don't see why it wouldn't.. VT-VZ fuel tank is the same piece irrespective of model (except of course for the extended range tank of course), so a V8 pump should drop in.. As long as it flows the same or better than the standard pump, it should work fine.
