Technician: Curtis B., Technician replied 11 months ago

If you open bleed screw past the primer pump, do you get fuel when priming? From the sound of it, you may have a blocked fuel line at tank, or up to the fuel strainer. Also could the fuel strainer you just cleaned be leaking, not letting the primer pump suck a vacuum?

All lines and components before the primer pump have to be vacuum tight and open. Everything after the primer is under pressure and would not cause this.
