A few weeks ago the plastic fuel/oil nipple at the motor cracked. This part is no longer available, so I used double barbed end fittings to rejoin the oil and fuel feed. I squeezed the primer bulb for the oil several times and it felt hard, so I figured it was ok. I ran the engine on the hose at idle with no issues. I am in the process of selling the boat, so we took it out for am sea trial. 8 seconds or so after we reached 4000 rpm or so the no oil alarm went off. we immediately went back to idle and I squeezed the oil bulb a few times and the alarm went off. this happened 3 times. After that I was able to run full throttle for a mile or so with no alarm, so I figured at first it wasn't primed, but was now ok. A week later at the house I ran it on the hose and quickly accelerated the engine a couple times up to 2500 rpms and the no oil alarm came on. I removed the oil hose from the vro pump and there was maybe 3/8" of air at top of the hose and no oil ran out of the pump. I squeezed the bulb and pumped some oil into a container. There was no air and I made sure oil was up to top of hose and reconnected. Started on hose and repeated what I had done before and no alarm. Checked hose from engine down to tank and doesn't appear to be leaking. I was thinking the oil line may have had a leak and the pump lost prime. The fact that the problem didn't appear until I disconnected the line and got air into the line, leads me to believe that the pump is fine, but not sure. I'm gonna let it sit a few days and try again and hopefully put it in the water to make sure its ok. Someone is supposed to come look at it next weekend.
Anyone out there with any good advice? If the problem repeats, and I can't it resolved I may have to buy a new pump, but at over $400 dollars I want to make sure it is bad. I know they sell rebuild kits, but I think I read that they are only for repairing the fuel side of the pump.
Any advice or suggestions would be greatly appreciated.
Thanks
