Fuel vapor valve
Need help, how this valve work (part number is 90917-10020)?
I have problem with high pressure inside fuel tank. I checked vapor hose, it is not blocked, but I do not understand valve operation. I can blow inside tank, but the air cannot pass outside to reduce pressure inside tank , is it OK? So it is one way valve. Is it normal?
