Another overnight on Aeolus and made progress on diagnosing and fixing my engine dying problem. Previously, I reported on my suspicions with a vacuum leak. On this trip, I brought along my clear hose and installed a stretch between the existing three way fuel valve and the Racor 500. Sure enough, when I turned the fuel pump on that draws suction on this side, I was getting air bubbles. I would get more air bubbles when I switched the valve off and on, simulating start up.
So I installed the new ball valve style and connected the same clear hose and no bubbles. Hooray!

Going forward, I still have several projects to do. I will replace the ancient Racor 200 backup filter that is really nothing but trouble. The priming pump doesn't work anymore and is likely a source of vacuum leak, the ball valve nightmare I've written about before is a poor design, and since I already have a Racor 500 I can avoid having to store different types of filters on the boat. I already have the new Racor 500 with a heat shield on order. I also have an additional three way ball valve to replace the second of that style in this system. For all I know now it is also a source of vacuum leak, but I haven't tested it. Doesn't matter, I don't trust those and it's getting replaced.
Also going forward I will routinely open the bleed valve to siphon off any accumulated air that SHOULD NOT be in the system anyway.
While aboard I also installed my new PVC oil catch can to reduce the amount of vaporized oil I was feeding into my air intake. I found it oiled up my KN air filter too quickly and don't like the thought of whatever it was doing to my intake valves and combustion chamber.

| New oil catch can installed. You can see the direct route from the crankcase breather. Ater taking this photo I ran the output back into the KN Air filter that has a hose fitting mounted into it. |
Also finished up installing heat shrink on the newly formed terminal block crimps and then lightly coated each junction at the terminal block with No Ox ID Special A as that area sits in a bath of crap.
