My girlfriend said I should get a locking cap for my truck. I said now they drill the tank. I would rather replace the little bit of gas I keep in it than to replace a tank too. I only use my truck to pull my boat to a ramp about 8 mile away. I probably never put over 1/2 a tank in it.

There was a story here last week about some theives stealing a thousand gallons of gas from a local gas station in the middle of the day!

Where in the hell do you put 1000 gallons and how do you do it un-noticed? Something smells fishy.

As far as the boat, it's 40 feet in the air at my marina. Hopefully my gas is safe there.

Now correct me if I am wrong but wouldn't it be really easy to just take the screws out of the flange? That defeats the whole purpose.

If you can gain access,thru bolt w/self locking nut's.
Nice looking cap C.P. !

1. Through bolt.
2. Most fuel full lines don't have a lot of slack in them, and are semi-rigid. As long as you have a couple (should have at least two) hose clamps on tight, you would not be able to lift it out of its hole.
