I need some help with my 1988 mercury 80 hp outboard. I just rebuilt the fuel pump and in doing so iI had to replace the hose from the oil pump to the fuel pump. I put a clear hose on so I am able to monitor the oil. Now when I start the mtor the oil only goes about half way up the hose to the fuel pump. Is them some sort of priming method iI need to do or do I have a bigger problem. Please let me know whatever you can. Thanks.

I had one of similar vintage. I got it new. The dealer strongly advised me to mix the oil at 50:1 in the tank. I did so and never had any trouble. Some other folks experienced the problems that come with inadequate oil flow. I never put any oil In that reservoir, always 50:1 in the fuel tank.
