Fuel Cut off Tap

Has anyone fitted a petrol fuel cut off tap on their rib, if so any pictures and how to do it please.

Not really necessary, I'd think, as most boat fuel systems are not gravity fed.

Shut off the motor, and fuel stops flowing.

Any particular reason you were thinking of installing one?

MCA coding requires a fuel shut off??

I've got one here-it looks like it screws into the thread for a water seperator. Have a look at the charity auction-there's a pic of it there.

Just finished fitting them onto the water separator outlets. When priming one engine fuel would run out of the other if it was tilted. Has solved problem. Will post pics later.
Watch the types of threads, the valves I bought had gas threads but the water separators where NPI, very similar but slightly different pitch.

Sorry thats what I meant to say, National Pipe Thread, seems to be used on many fuel connectors.

Yes most kit from the USA will be NPT

Dont know if this arrangement would be much good for an emergency cut out as its pretty close to the engine. Tried a change over valve but difficult to find a good mounting point for it. Outlets to main and auxiliary both have ball valves, inlet is at the back.
