Josh,
I am impressed with your video and may copy some of your mods next season. Where is your seawater strainer? My Racor is in the same location as yours but my seawater strainer is above and slightly forward of it. The seawater lines run from the inlet valve to the strainer and back to the raw water pump along the port bilge.

The original vent was just a knurled knob on the outlet sife fitting. It wasn't even at the highest point of the filter housing and didn't allow catching the vented fuel. I started thinking about how to maybe get a higher vent point. First I drilled and tapped a hole in the top of the housing and put a typical brake bleed type of fitting. It worked but necessitated using small tubing to direct the vented fuel into a bottle. It wasn't until I performed this mod that I realized just how much fuel needed to be vented in order to flush all the air out of the filter. I was usually looking at about 1 gallon of fuel just to get all the air out. I started thinking about how to direct that vented fuel back to the tank. I was going to run a return fuel line when it occurred to me that the engine already has a return fuel line from the injectors. I changed the bleeder valve to a t-handle valve. Then I inserted a tee fitting and t-handled valve in the return fuel hose. Then I connected the 2 t-handled valves with some clear tubing. The 2 t-handled valves isolate the vent tubing during normal operation and maintain the integrity of the original components. When venting, both t-handled valves are openwd to create a flow path back to the tank. You can watch the air bubbles in the clear tubing disapate as the vent continues. See my video at about 2:10 minutes. https://youtu.be/H-GI38vE4hQ?t=2m12s These engines take a 2 micron engine filter and I run a 2 micron racor. The racor is now easier to change and bleed so I prefer it to clog first. I also show a vacuum gage which I installed on my racor in the video. A new racor filter has shown to have very low vacuum so whenever it starts to creep up I change it...hasn't happened yet. Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
