Servicing a Vapour Separator Tank (VST)

In this video remove the vapour separator tank from a Mercury outboard to clean it and show how it works. I also use a fuel pressure gauge to test the high pressure pump while the boat is running. Problems with EFI fuel pressure are easy to identify using this tool, it is then a matter of finding the cause.
