I reinstalled my rebuilt 787 into the boat on Feb 7th. The day before prior to install I replaced all the oil lines, primed the pump with the drill until I had oil drip into the manifold, new oil filter and everything went perfect. I put the feed line and the filter on the motor, so I could just hook it up to the supply line without losing any oil that fed the pump. So motor in and lines all purged and I had to stop for the day. A few days later I had an hour so I hooked up the cable to the oil pump and finished connecting ground cables, positive cable and the connectors into the voltage reg etc... So last night, I was going to put the carbs back on, and I noticed the one 3/32 line to the mag cylinder is empty, yet the other one is still full. I have a little oil residue on the bottom of the hull, but I had that before from when I installed the engine and spilled some. So I can't tell if that line leaked, or if it somehow lost prime. I plan to spin it over and hold open the pump to fill the line and then see if I can find a leak at the pump or the manifold. I searched the forums, but couldn't find any reports of this. Thoughts...?
