Thread: Anti theft Mod

Long time ago when I used to buy a few vehicles at auction for resale I acquired a Valiant VC slant 6 auto. Nice tidy car and I drove it for a while before selling it. It had, I found, a key operated fuel valve in the tank to pump line with the key socket just in front of the driver's seat and easy to reach once seated. Never seen another one but I did think it was a great idea. You could start up and drive a few hundred yards before the Val snuffed.

Like Bigbjorn, I had a three way fuel delivery switch in my Series III LWB 2.25L. It wasn't designed as a theft preventer (seriously, how could you theft proof a SIII when you could easily start it without a key?). The switch was just under the drivers seat squab, visible but not really noticeable. When pointed to the driver's seat it opened the drivers fuel tank and when pointed to the passenger seat it opened that tank. If you pointed it down it closed off both tanks.
So I simply pointed it down whenever I left the car, figuring that when the car spluttered to a stop once the Zenith carburettor had emptied, the thief would give up and **** off. Added to that, I also left the transfer case in neutral, so he'd have to sort that out before moving.
Caught myself out a few times, but, when the motor started to splutter, simply turning the fuel cock to a live tank gave the mechanical fuel pump enough fuel to replenish the carburettor so quickly that anyone following would have probably not even noticed that I had slowed down a bit for a few seconds.
Can't do that with a D4!

Wonder if this hidden 3 way valve system was a common or Qld thing as we had an open top 40 Series LC from Qld with exactly that system! We took it out hoping someone would steal the POS☺

This thread also reminds me of a colleague who had a troublesome V8 RR and who left it with keys in doors open on the Bass Hwy hoping it would be stolen. It never was😎

My '84 RRC still has a key-operated fuel switch in the floor under the passenger side mat, fitted prior to my ownership. I used it the few times that I night-parked in Sydney many years ago. It was a better option than removing the rotor button of previous vehicles.

Solenoid in the fuel line were common in the 80’s.

Many had a touch pad that needed a code before the solenoid would energise.

We had them in all our work vans back in the day,when car theft was on the rise and Fords were very easy to steal.

Often the thieves would wander around with a bunch of Ford keys and find one would work.

Once the vehicle locks had a bit of wear,many different keys would work the same lock.

I've been thinking the best deterrent for our Defender might simply be something really obvious like a chain around the steering wheel and down around the pedals, with a padlock. A bike chain the right length with a protective sheathing would not scratch the steering wheel. I use one to secure a solar panel from theft while camping.
I'd want it seen before they even tried to get in the vehicle. That might deter some amateurs who would not normally carry cutting equipment or tools to undo the steering wheel. You'll never stop the pros.
This method is cheap, simple and doesn't require any fiddling with the electronics, which is good.
The disadvantage is it would be annoying to have to fit the chain each time, but I could live with that.

For Defenders you can buy a plate that fits over the pedals

I was going to say transfer case in neutral , but beaten to that,
or B.
Let rottweiler sleep in car at night.
