Anti-Theft Options on our 67-72 GM Truck?

Possible? I suppose. Anything is possible. It would be tough. The seal is very tight, and there isn't a good angle to get on it with a hammer & tool. But yes, it could be done.

I don't care what you do - if someone wants to steal your gas, all they have to do is crawl under your truck and run a hose to their catch can straight from your line that runs into your pump. Then it don't matter what kind of system you have implemented, you are dry.

Gravity isn't the issue either, ever heard of a siphon?

There are measures you can take - but NOTHING is foolproof.

Just like a house - you can guard every window, door, and entry way 6-ways to Sunday - but with a cordless sawzall, you can make a new one anywhere you want.

As far as alternate caps...
I have one of these.

So far so good.
It'd be pretty tough to get into without the key. It seals really tight with an O-ring.

I'm with ya' on alarms, very few people even pay attention to alarms going off. I like the look of filler caps such as yours but it looks a lot like the cap on my boat and those keys are easy to get if they are similar to marine use.

Hey Orange,
Does this cap attach right up to our truck gas tank stem? Did you have to modify anything?

I will check on this too. Where do you think I may still find this at? I will ask the local For? Dealer.

I'll go check out the part number when I get back to my truck weekend after this one. I would imagine a Ford dealership may have them, not sure. I found it in my great-grandparents garage (my great-grandpa, rest his soul, was a train engineer and gear head, lots of cool stuff is buried in that garage), and kept it because it looked cool on my desk.

It fit really tight on the neck. And enough so you had to push it down to get the key to unlock. The only way you were going to get it off with out a key, is if you could drill it, and only hope it comes off that way.

Thanks. I would love to check this one out in action. Old garages are always fun to go thru. It seems like older folks had cooler tools too.

If the problem is happening at home try a camera system. You won't stop them the first time but it will give you a picture of the sob. My guess is they know you. know you keep gas in your truck and probably when they can hit it and not get caught.

[joedoozer]

Locks only keep honest people honest. If someone wants something bad enough they will steal it. I suggest chaining a dog to the bed haha.

[stonewall618]

heres what i would do if i started to notice my gas being "missing"... you can get an old under the bed gas tank and mount it right on the frame... the place you would but the gas in would come out in side the wheel well... i was thinking about doing this so i can stop sitting on the "BOMB" and its a cheap solution to a big problem...oh... you also get about 6inches of leg room if you play your cards right

[Huck]

With my luck, if i used the "fill with Diesel only" the first time my wife drove it would---well you get the picture ---jewel's!! (pirvate joke!hehehehehehhe).
I like the little basket solution--- but if they want something bad enough--they will find a way.
Leave an old gas can in the bed with a hand full of sugar cubes mixed in with the gas. When they pour it in their tank, the sugar cristalizes in their carb, valves, pistons, cylinders etc. You will know who is the thief when you drive past them--wave, ask they if they need some help---have another can of sugar gas and give them this too! they will think you are a nice guy and stop stealing your gas!!
Now how do I know this----let's just say I'm one of them old guys who learned some from other old guys! Huck

moth balls do what?

old car lor theif gets a mouth full of the suposidly toxic mixture and is not very hard to find the next day

[longhorn70gmc]

WOW Guys,
You had me on the edge of my seat reading all of these. There are some really great ideals. I am going to look for a diesel sticker now. I like the basket ideal, I will mess with that and see what I can brain storm. I thought of the parking close to a building or other car. I will do that when the Longhorn comes out of the garage. The picture of the dogs were cool. I am working on the wife to let me do that to. I will have to teach him to like the bed of the truck. Picture camaras are in the future. I have no street lights out here. I live in a new developement part of town. Thanks everyone for the comments and suggestions. You all, and the ideals is what makes this place great. Even though the gas got stolen, I refuse to give up my trucks. As always more ideals and talk on this is welcome.

Huck's idea could also be used another way. Instead of putting sugar cubes in with the gas, mix in a little bit of bleach. If you've ever seen that episode of Mythbusters where they did car myths they put bleach in the gas tank and the motor did not sound too great when they ran it. They let the gas/bleach mixture sit in the gas tank for the night and the next morning the gas tank was rusted.

that reminds me of the rig my dad made a while back that i lovingly called the siphonator 5000, from an old electric fuel pump that he used at the pontiac dealer ship to siphon out some of the tanks when he had to do tank repairs so they weren't so friggen heavy to drop and put back in. i'm a fan of the hard/sharp pointy implement and mean guard dog idea, but the basket idea is a good one too. maybe weld some sort of bracket along the frame that covers the fuel lines all the way up to the pump.

They also put the sugar in the tank and nothing happened.

I dont think they will get a hose to my tank. To many bends.

The Cool Cap does require modification.
It does not attach to the stem that comes out of the tank, it sits flush on the side of the cab.

Best pic I have right now.

You can see that it's flush.

That is cool ORANGE. I like how it sits with the cab. Thanks for a great picture.

I wondered how this would work ever since I first saw these caps. Looks nice.

Back in the '70s when gas first went up auto parts stores sold an inti siphon coils spring device to insert into your fuel filler.

[89 crew]

street lights are not necessary for all cameras. Take a look at x10.com I do not personally have one of their systems I went for the big dogs, and guns.

[cowboyup1086]

i took 6 pieces of 6" long by 1/2" wide stainless steel rivited it in the middle, spead the out bent them oposing ways 3 on one side 3 on the other and put it in the hose between the tank and the cap, never had gas stolen again

[krue]

I just keep mine empty most of the time.
