Fuel Cut Off Solenoid?

I fitted a large fuse to protect the wire, I think they solenoids are rated at 1 amp, so I used what I had which was rated for 10amps which I think, but I am not 100% certain, was 18 gauge. I can lookup this up, but not at the moment, so probably not a huge help.

 

What do you use to reduce down from 8mm side?

Edit: scratch that just re-read your leccy pump is in that range.

 

Great thanks...

 

Poor man's 8-6mm reducer is a cheap fuel filter or snip the end off and use that if you don't need a filter in that location.

 

Worth testing it works, checked mind again yesterday pulled the wire off, fuel pressure dropped. There's no point having one, if it's not setup right; they have a bypass lever on them in case it fails closed.

 

Mine is similar to the pic in your original post - 12 quid job off fleabags. I thought the lever was to manually shut it off, as a security measure. Haven't tried it yet but have I got that wrong?

 

I think it's to open it up, in case the solenoid fails, but perhaps it does both?

 

I'll have to try it now. Later in the week anyway. I'll report findings.

 

Does both, I think.

 

Given its location under the fuel tank, if wouldn't be my first choice of anti theft device, it's a bugger to get access to it.

 

I wasn't proposing its use as an anti theft device though anything that makes it more inconvenient for the thief is a plus. I regard the manual switch as an override for when your electric circuit fails, eg blown fuse, corroded connection. It will restore normality to get you home. If you want to use it as an anti theft device, best to conceal a switch somewhere that is convenient for you to access but hard for the thief to find. Could be a dummy radio switch or something like that.

 

So why are you fitting one? I had this idea on mine that maybe there's a leak somewhere and a cut off would help me discover it. Fuel consumption is quite bad when I don't do a lot of miles though it didn't used to be like that.

 

I fitted mine, a few years ago, as a safety measure so that if anything went bad in the hot cupboard, the fuel supply would be cut off as soon as the ignition is switched off.

 

The lever is a bypass rather than toggle, ie you can't force it shut. What you can do however, is put an easy access switch in the earth.

^this. The main purpose of a fuel cutoff would be to stop the tank emptying itself into the engine compartment if a fuel hose burns through in the engine room. Only reason I fitted one.

 

Scary how quickly the fuel pours out under gravity when you pull the pipe off the pump infeed.
If you fit an anti-theft switch there's enough fuel in the carb to start and drive off a little before all the crap at the bottom of the carb float chamber is sucked into the carb, blocking the jets.
So proper anti-theft.
Someone's done this twice

 

Wow! Out of interest how far did they get?

I would as @mikedjames about how much fuel pipe you need, I don't have a stock Type 1 to measure. Don't forget to source two extra fuel clips
