Did not work as expected.

I was told that the item needs pressure to work properly. I have an electric pump (pressure), but if the nozzle valve doesn't at least open so air can escape before the flow of diesel then it wont work. One would need some sort of purge valve near the nozzle, that would be messy. I have no issues when using a manual nozzle, the valve opens which allows the flow of air as the pump primes and then fuel. Its possible mine was defective, the auto shut off would click on as soon as handle pulled.
