Source for fuel shut off solenoid?

[Jimmy]

I've been crawling around the internet, looking for a fuel shut off solenoid. I can find numerous products, but none that I would be willing to install in our application. Has anyone found/installed one with success that you would recommend? Obviously "explosion proof/ CSA / Coast Gaurd approved is required. Assuming it exisists, I think the proper location would be just before fuel pump?
Background - always shut the fuel of on top of tank, but that involves asking someone to move and inserting myself, deep into the port lazzaret. I like the idea of killing the fuel, during a day sail, and a "flip the switch" solution is ideal, for both shut down, and start up.

Cheers

Access to my tank cut off valve is under a hatch in the quarter berth, a real pain to get at. I installed one of these about a 10" away from the tank on the galley bulkhead with the inlet to the valve and hose between above the top of the tank so if the line splits it will not siphon fuel into the bilge. Fit perfect, I just capped the secondary port on the valve but it is nice to know I can add a second tank.

Manual fuel valves are easy to find. What the OP wants is an electrical solenoid valve.
These are not easy to find and introduce a new failure mode too.

Quite a variety offered here: http://www.12voltfuelvalves.com/12-v...ff-valves.html

Not to raise a sour note here but I like the idea of a manual shut off fuel valve near the fuel pump because it makes you get your nose in the engine area.

My 1977 Pearson 323 came OEM with a fuel shutoff solenoid valve mounted right on top of the tank. It was manufactuerd by FuelTrol, but I don't think they're still around. Perhaps you can find one off of a salvage boat.

The OCD mechanic in me has to agree. However, I can relate to the idea of how cool it would be to shut off the engine, flip a switch, and raise the sail while the lady reclines on the cockpit cushions in her bikini undisturbed as she watches you master the ship under her gaze.

Try the old barnstormer's trick.
The pilot and the lady are out for for a night flight on a warm spring night under a full moon. The pilot, unseen by the lady, pulls the choke out and the engine sputters to a stop. An emergency landing in the near by meadow becomes a necessity. The pilot fiddles with the engine. No start. There just happens to be a sleeping bag on board............
After a couple of three hours the pilot tries the engine again. What do you know it starts. They fly away.

Imagine how cool you'll look motoring down current toward a closed drawbridge and the electric supply to your snazzy valve quits for any of a variety of reasons. Added complexity brings added risks. KISS

Then you do the quick U-ey, drop the hook, save the day, and the Lady fairly swoons...

Well, my lady appreciates an outing that's trouble free. So do I. Kinda hard to impress when your keester is sticking out of the engine space while you're troubleshooting.

Jimmy.
I think the relative height of each part of the fuel system has to be considered when choosing shut off locations. If your fuel line leaves the top of the tank and drops down below fuel level, say to a filter, then up to the pump the shut off at the pump would not protect anything up stream. The shut off at the top of the tank would also have to be closed for full protection.
Had to deal with this when I rearranged my fuel system.

'zactly! (Neil forgets to point out that plumber's butt probably adding to the scenario)
Manual valve is the way to go.

OK Guys, hang in there with me......
Attached is how I plan on building the fuel supply side.
Fuel Tank - Manual Shut Off - Solenoid Shut Off - Water Filter - Fuel Pump - Manul Shut Off - Polishing Filter - Pressure Gauge -Carb
Thought process is
... solenoid is there as a temp shut off ( sailing/engines off for a few hours)
...second shut off allows for easy filter change.
I do realize there are numerous conections, and every one is a possible leak/issue, however with double clamping and a little attention to detail, I can think this would work well. Please have add it....I'm open to suggestions

(John- Thanks for the imput-I have always sniffed the "exit" coweling, after starting blower, and prior to turning the key, so checking for fuel leaks is in my routine too. ( Just dont want to crawl into the lazz every time))

(As for the old Pilot trick, SWMBO would last about 60 seconds, before wrestling me for the tools.........hey wait.........that might work!)

I have posted previously about the electric solenoid fuel valve I purchased for my vessel...all rated for gasoline and the marine environment.

(Should point out that the system I made has a manual reroute line in case the solenoid conks out.)

Nobody has mentioned this yet: Inspect what ever set up you have regularly. Out of sight out of mind is not a good idea.

When I replaced my original rubber fuel line that came with the boat with ethanol rated hose many years ago there were some severe cracks in the old line. It didn't have much life left in it. If the tank shut off valve would have been open when the line cracked through all the fuel in the tank would have been siphoned into the bilge. This is why I always close the valve at the tank.

There is one advantage to a fuel shut off solenoid (assuming it works correctly): You don't have remember to open it.
