Hello, I was told I may have a faulty fuel pump on my Johnson 225 yr2000. I took the top hose off and started it and a steady stream came out. Is this what suppose to happen or should there be a jet coming out.
Sounds right. If the pump is working properly, the diaphragm pulses rapidly giving what would appear to be a steady stream. It would not exit under high pressure, however. Check your manual, but expect 2.5 -3 psi at around 4000 rpm.
A VRO pump will not issue a steady stream unless it has a air leak and is rapidly pumping...this will also cause over-oiling/foamy oil and excessive smoke,hard starting idle issues.
