human lips blowing here/?
benzine is a solid known cancer agent, best is use long clean hose here. to blow.
the gas cap must be removed (it is solid block here) if removed the return like is 100% free flowing and if you blow now it must be.
as the gas cap block and the vent regulator takes over 1 PSI to overcome, humans do not do that well, (no ex GF jokes here)heheheheeheh
on a running car ever drop of fuel leaving the pump comes back to the tank, (return) minus what the injectors used.
so there is no return line pressure then. (it is less than the feed line)
but key off, not true. (gas cap off is he trick here)
1PSI , due to evap pressure regulator stoppage.
