Deuce locking fuel cap

[RAYZER]

Ever wonder what if ? when some Hater would sneak up and stick a waterhose in your tank ? Or take a wizz in it ? Or sneak up at 3 in the morning and siphon out all of your precious peenut oil ?

Well heres what i came up with to help prevent such catastrophe

materials i used: 2" x 1.25" angle, 3/4 x 3/8 bolt with nut, piece from deuce upper exhaust stack bracket .

mocked everything up to fit, welded nut so could'nt be taken off, welded angle to fuel tank strap and walah! Zombie proof fuel tank!

( caution ! take fuel tank strap off before welding on it ! ) Dissclaimer: not responsible for any exsplosions!

ps: Deuce da kat

Deuce the cat should be all the security you need.

 

[TexAndy]

Pretty slick.

Someone could still just unbolt the strap, tho. Or if they were interested in stealing fuel, drain from the bottom.

Get more guard cats.

 

[DieselBob]

Nice job. I like the simplicity.

 

[tigger]

I think the cat was the job supiviser.

It would be poetic justice is someone drained a tank full of WMO into their fancy diesel pick-up.

Like my daddy used to say (last week it was), "You can't stop a thief unless you use enough lead, but you can keep an honest man honest with a decent padlock"...

 

[RAYZER]

ya but, if the system was defeated you would know and then you could go from there, if a defence was not in place, then you would'nt know and THAT might be bad.

 

[velociT]

Seeing as how I've never welded on anything before...


I'll save my old fire department the trouble.

I agree with the others about getting another attack cat. The ya gotta make a sign:

"Warning, Fangs on Duty"

Like the idea, nice and simple! And it does give you an idea to check your tank if some idgit tries to defeat it!

Anybody caught on my LZ after dark is subject to a terminal case of lead poisoning.

Yep been using one very similar to yours for 10 years now. There was a thread or two on different style fuel locks some time ago.

i like the way you did yours,very nice!

 

[Billy Bobbed]

Get idea thanks

Rayzer--I kind of studied your pics and first off, that's some nice work. Have some questions, and before I ask, I assume all risk of blowing myself up. Now, having said that, and in a PURELY hypothetical vein, can't you just undo the strap bolt, lift it up, put down a welding blanket that's wet over the tank, and weld it up? Or a piece of plywood? I like your work. I may do this with my suggestions, in a totally hypothetical way, of course.

Maccus:

Does your Fuel Filler Lock Bar pivot on the Fuel Tank Strap Bolt when unlocked?

This seems a simple approach without the need for welding.

Although, yes it can be released with a wrench, it is still a simple deterent to keep the honest man honest. A determined thief will find an alternate means of ingress/egress.

ok, thought about what to post in reply to your question westex, and my answer is NO, i would caution anyone not to weld around fuel, though diesel is somewhat non exsplosive , some multi fuel owners run wmo mixed with gas,

KABOOM!

so stay on the side of caution and safty and take that strap off before welding!

... I doubt there are two caps with the two vertical tabs attached in the same place on the top of the cap. I must have a dozen caps around here and all have the tabs located at different positions. So you have to make your strap to fit the cap you use. And more than likely should you replace the cap the strap will not fit correctly.

AGREED - I already KNOW that mine are oriented differently than those shown. They are "nicely" aligned at the "horizontal" 9 o'clock & 3 o'clock positions.

Thanks again!

 

[RAYZER]

and there are i think 3 different positions that the cap will go on.

We have had a real problem with fuel theft in Michigan. My boat got drained last summer 110 gallons so i set up a sting operation cought a guy twice my age. I asked is this your boat he said yes just transfering fuel i laughed and called the cops.
"wmo" in my deuce see how far that will get ya...

A piece of damp plywood or a welding blanket even dry should be fine. Forget all that hogwash you see in the movies about diesel tanks getting a spark and the huge movie explosion. The simple and unentertaining truth is DIESEL DOESN'T EXPLODE! An old neighbor of mine used to work in a truck stop and when a driver would come in with a cracked fuel tank (back when they were all hemmed sheet steel), he'd pull the bolts out of the clamps, turn the tank till the fuel stopped dripping from the fracture, then wipe it off with a rag, fire up a torch, grab a braising rod and his shades, and laugh his butt off at everyone around running in terror as he braised the crack closed. then he'd just smooth it off with a little emry cloth and shoot a little spray paint on it. He lived to a ripe old age of 79 and would have gone longer if it weren't for cancer. My point being that unless you've got a Multifuel with a considerable amount of gasoline in your fuel mixture, it will only combust under compression and heat, just like in the combustion chamber of a diesel engine. I would lift the strap before welding just to save the paint on the tank. That would be the worst possibility for damage.
