Well, as far as I know, sidekicks are all fuel injected, so there's an electric fuel pump mounted in the tank. If your sammy is carburated, it uses a mechanical fuel pump mounted on the engine. But if your sammy is FI, then at least the tank mounted pump should work fine. Then it would just be a matter of physically mounting the tank into the sammy. I never dropped the tank on a sammy yet, so don't really know if the sidekick one would fit or not. You could always just get a fuel cell instead...
