Review on Scepter Fr1G501 Gas Can Gallon by Terry Wilson

The injector is a bit short but there is a trick to using it. Make sure it's really tight, turn the whole can upside down and then insert the spout where you're going to pour it (into the car in this case) and then use the release lever. It's a bit cumbersome, but doable. Hand tightening the nozzle is somewhat dangerous. To fully tighten it you really have to make a few turns where it appears to be closed. and if you snag some skin in the "safe" locking system, you'll get a good cut. So be careful.
