Fuel cut off switch

Recommended Posts

Some years ago I fitted an electric pump on my 3A but have never fitted a fuel cut off inertia switch. I am now thinking I should. Does anyone have any recommendations as to what switch is best suited?

Vist to a scrapyard with a pair of wire cutters, get as much wire as you can.

Ford Focus switch is a good option as its mounted on the side of the passenger foot footwell away from the elements

Thanks George,

By coincidence I was actually looking and wondering if a Ford Focus unit might do the trick.

It's what I use on my TR6, I think I paid a fiver for it from the local scrap yard.

Make sure that you get the wiring plug with some wire to make the connection to your car

Hi Geoff ~

I fitted my fuel pump cut-off switch under the dash near the steering column on my 3A.

This allows me to 'knock-off' the switch when I park the car for extra security.

In this position it's easier to re-set the switch if it operates under driving conditions.

I used this style. Land Rover I think

But I think Toms idea of having it to hand to reset whilst driving is a good idea. 
that I think I’ll do.

Here's mine under the dash, attached to the back of the brake / clutch cylinder inset.

Thanks Tom - that's better!

Got it off eBay some years ago. About £10 from recollection.

so do I take it that the red end cap is like a button that you can reset?

And thinking that this would be positioned to forward direction?

Just a ball bearing sat in a cup that completes the connection & gets knocked out with an impact, just press the red top cover to reset, as far as I'm aware it's orientaion in terms of front/back would make no difference to how it works....

Me too.   There is a second version with three wires, that will light a lamp on the dash to tell you thatit has triggered.

Useful if the "engine failure" you have just suffered is only due to mounting a kerb.  Won't happen parking but might at speed!

Yes John, the version I have has the third connection between the two wires shown in the photo to wire a lamp.

Before I installed mine I did some research (because I am not very good with electrickery) which suggested that the two wires were specifically positive and negative. From recollection there was nothing so simply as + or - stamped next to each wire but a letter code. May be relevant if you get one of these.

I can't recall how mine is wired.   I worked out which was which on the bench, with a couple of lamps, knocking it against the bench until one went out and the other lit.   If anyone wants, I can go and write it down!

If you get one, if at all possible get the connector to the loom as well, with the wires cut off long.     The pins in the switch are not ordinary spade connectors, and it's much easier to wire it in this way.

A friend of mine recently got a tracker for his car ( a very common low cost item - model TK103).

Apart from using it to locate the car it has many other functions available, one being an “SOS button”.

The 3 wire inertia switch would be an ideal “Sensor” to replace the button.

What happens is that if the inertia switch is activated a text message is sent to a mobile phone (as specified by the user) with the message “Help Me !” and a link to google maps with the location of the car.

Possibly a life saver if you end up in a ditch on a remote country road. The message is repeated every 3 mins. until the driver resets the tracker.

Would these later inertia switches be seen as an upgrade to the standard  tr6 standard inertia switch.

I would definitely trust my life with a new switch - value myself more than having a switch that looks original as surely most folks on here would. I've heard that the old switches weren't that good anyway rusting up inside and sticking apparently - so my classic mechanic tells me.

Keep the old switch in its standard position (but not connected, just dummy wires) for looks/originality and install the new switch & relay hidden away somewhere.
