No start on pickup. I installed new lift pump. Flushed fuel tank, new filter. Put in new fuel. Checked all fuses all good. I hooked up gauge to schrader valve and cranked, I only could get 10 psi on gauge even after extended cranking. I blocked off return lines and cranked, stopped cranking when gauges hit 80 psi. Replaced regulator kit and tested, no change. Is there any easy way to bypass the filter bowl to test? Anybody had problems similar?
