As for the engine, I am perplexed. I drain each fuel filter of water
(there is none), inspect the water-separators and find them clean, tighten the
throttle linkage and while those efforts made a difference, now the engine
"hunts" at idle, and remains steady and strong at power.

Hi Lee:

I am almost convinced that the problem resides in the fuel valves. We had
exactly the same symptoms on the INDIFFERENCE for some years on and off. You
have completed the inspection of the usual culprits but discovered no
problem. Concentrate on the valves.

Let us know your findings when convenient.

Regards

Leonard Stern.

Hi Lee, and All,

The only vacuum rated valves that I found to be commonly available when
I installed a fuel polisher in the Celestial are Conbraco's Apollo
valves. I had many troubling episodes with air in the Celestial's fuel
filters. I made a 'Jumper" out of clear vinyl hose to fit in between the
hoses and valves and conclusively proved that the air was coming in from
the valve stems on both the original valves and the valves I had
purchased from a Big Box store. I searched online for vacuum rated
valves and found none except for exorbitant prices. In a previous life I
worked for GE on a Navy contract that had vacuum systems and remembered
that the only valves they used were the Apollo valves, but thr webpage
did not indicate any thing about vacuum pressures. I called the Conbraco
tech department and asked about vacuum rated valves suitable for the
fuel system. He said any Apollo valve would work, so I replaced all the
valves with Apollo 32-100 valves and have never had any more problems.
(Knock on wood) The following week I checked Conbraco's webpage for
Apollo valves and noted that they indicated the vacuum range that they
were suitable for. (See excerpt from Conbraco's webpage for Apollo
32-100 series valves,below - specifically the last line.)

Wayne, et al.,

The problem that I experienced this past cruising season with air getting into the fuel line and shutting down the engine when at idle was traced to me being stupid and not fully torquing the all 8 bolts to the fuel-water separator system’s top.

Wayne, I have had these fuel valves for years so I was wary to blame my problem on them.

As it turns out, when I went to the supplier let week and asks for the spec sheet, he needed to know the color of the valve handle. I told him I had nearly all blue and one red.

Turns out the blue valves are tested at 24 bar and 29” of vacuum. The red is tested to 12 bar and 28” of vacuum. (Now I know why the red was cheaper than the blue.)

Gray and white are tested to pressure only and I have none of those.

So, not knowing the above, when I went to get the fuel system piped years ago in Çanakkale, I now understand why the hydraulics fitter was asking me so many questions about LeeZe’s fuel system and wanted a schematic. And then, when he said he would have the valves in the following week, I did not give it a second thought.

I was given a choice of blue and red valves, and chose blue because blue represents diesel, and the red valve is only used for the bypass valve to the dual fuel-water separators and it is a NC (normally closed) valve.

Thought some might want to know how this all worked out………
