Bypassing the oil injection

[guy48065]

This question concerns my 2000 Johnson 40 on my pontoon boat.
I decided to eliminate the oiling system so I cut the oil line entering the motor & plugged it with the plastic plug provided for that purpose. I then removed the oil tank, hose, and wiring. I unplugged the harness from the fuel/oil pump to disable the No Oil warning. Lastly I filled the tank with pre-mix and flushed out the fuel hose.
Hopefully I did this all correctly.

Now that the boat is in the lake I'm having trouble with fuel starvation. Any chance that plugging the oil line to the fuel/oil combo pump can affect the fuel side?

Get rid of the plastic cap covering the oil line. That is for servicing not permanent use. Take a piece of the oil line and put s bolt in it then clamp both ends of it. You are probably sucking air in on the oil side. You also want to make sure all the hoses are securely clamped.

Looks like my problem was the 2 year old fuel hose & bulb. The bulb would get hard when pumped up but then wouldn't squirt gas when the spring-loaded ball was pressed in. I guess there is something wrong with the check ball, or there's an internal restriction that wouldn't let fuel flow to the motor.
Replaced the hose and now it runs WFO as long as I want to.
That hose is a USCG approved, EPA compliant assembly I paid a premium price for 2 seasons ago. Junk.
