Valves jammed and unusable within a day.
I bought these as a temporary fix to stop the diesel fuel flowing back into the tank and causing an airlock on my car whilst I got a permanent repair carried out. It worked great for the first day, but the next morning fuel wouldn't flow through it, I removed it and I was unable to blow air through the direction of flow. I replaced it with the second valve and the same thing happened the next day.
