New to this forum and my 2004 BF225 so sorry if this is a bit of a basic question...
I can’t find anywhere that explains in detail how the VST works. I think I understand the basics: low pressure/lift pump feed to VST with float switch feedback, High pressure feed to fuel rail, pressure regulator feedback. But what else is going on and where does the vapour part come into it. Are there other fuel feedback routes into the VST from the fuel rail? I was looking for a diagram with a step by step explanation if anyone has something like that.
i want to do my own servicing and so want to understand this as best I can.
