I am going to start up a freshly rebuilt 2004 Johnson 90 hp V4. I'm wondering how to tell if the oil is reaching the VRO pump when the primer bulb gets hard.
I know that my 1994 40 hp Evinrude has a small section of white plastic hose (1/2-3/4" long) in the oil line just one inch or so from the pump. So it was easy to tell if the oil had been pumped up to the VRO pump.
The 90 hp does not have that piece of plastic hose (that I can see or is listed in the service manual). So the best I can tell is where I connect the VRO tank to the hose coming off the pump. That length of hose from the tank to the connection point is easily about 18" long.
Any suggestions to know if the oil has reached and filled the VRO pump before starting?
Thanks!
