Gas tank getting pressurized
I am very much inexperienced. I had a bike once before but it was about 20 years ago. I recently purchased a Vulcan. I discovered that it has issues after it has been running a while. Suddenly the RPMs climb significantly. Gas starts spraying out of fuel lines. Then it stalls.
It turns out that the fuel tank is building up significant pressure. Isn't a vent hose supposed to prevent that? If I open the tank after it has been running a little while gas will spray out.
Someone told me that it sounds like the return line may be clogged so my question is, does that sound like a reasonable assessment? If so, does anyone know of a video of some sorts that will point me in the right direction of how to handle it? I can probably just dig in and find it but would feel better about doing it if I had some guidance first.
