Fuel shut off

[GBowman]

Hello ev one

Im a new member, purchased my 292 Fastech last year. I noticed that there are no fuel shut off valves on my boat, is this normal? I've never owned a boat that did not have shut off valves and I have have owned a lot of boats!

Thx!

Have you checked at the fuel tank access cover on top of the tank? It is usually on top of the tank where the fuel lines come out.

I am not aware of any fuel shut off valves on any models other than the 45 and 48 yacht.
There are check valves on the top of the tank that will not let fuel siphon, but no shut off valves that I know of.

My diesels have shut-off valves in the engine room just above the primary fuel filters (Racor's).

Thx for the replies-I have traced all lines down and there is no shut off. I will be installing them this weekend, too risky not to have them and a simple fix. Im actually surprised that a boat of this caliber does not have them.

Thx again!

Why do you need them?
What would warrant shutting fuel supply off?

IMHO the only thing that would warrant shutting off the fuel supply would be a fire. On a diesel boat, an automatic system shuts down the blowers and fuel to the generator and the engines when the engine room fire extinguisher is automatically activated. This is accomplished by using fuel shut off valves that are electrically activated. They are normally closed (no electric current) and are energized when an ignition switch is turned on (necessary on diesels as they use no ignition system). It is all controlled by the Fireboy shut off system. BTW, it is available for gas engines also, if desired. Manual shut off valves are usually useless in the case of a fire as you probably do not have the time nor the desire to go into the engine room to turn them off.

Fuel shutoffs are very nice for service procedures. I have shutoffs on this 1989 357 SR1 but they may have been installed when the fuel flow meters were done. Changing the fuel/water separators with shutoffs is easier to restart the system, a lot less messy and just professional anyway. Isn't "professional" what Formula is all about??

Additional equipment drives up production cost and on a high pressure system extra parts in the line are more expensive than a simple clamp job. High pressure fuel lines have to be machine crimped and made to CG safety so it is a lot easier to just run a line with out extra parts and cost. I don't know if this explains Formula's position or not but this is reality in production.

If you want them install them. I prefer them myself.
