Does anyone feel the need to install a keyed fuel cap like we had in the 70s?
 
guess it depends on the rig. I’ve heard reports of people just going underneath and cutting the rubber fill pipe and syphoning from there, which of course would be much worse than having some fuel stolen.

... and they might just cut out the catalytic while they're there... what's a guy to do? :censored:
 
Thinking more about replacing the Stant fuel caps. I've seen postings about being the OEM cap stuck and finding an alternative. A keyed cap might be secured without over tightening, if that is the issue.
 
My opinion is the problem is frame of mind! If one click is good, three clicks is better!
 
I had a locking cap on my gasser. I’ll never know if it ever stopped anyone…. it’s long gone. On my clacker, both fuel doors lock and the caps are non-locking. For the relatively low cost, I’d certainly buy one ( or 2 if non-locking fuel doors) just for the piece of mind.
 
Locking caps on both diesel tanks and on the DEF.
Make it a bit challenging for stealing or adding anything harmful to the tank.
Another form of insurance and barrier to damage.
 
We had an incident a couple of years ago so I bought caps off Amazon. I usually only lock them if we are stopping for a night or more.
 
Fuel doors, locking or not offer a deterrent!
For the would be criminal to run down the street, gas can in hand opening every door on his way, to see what caps lock, becomes quite obvious.

Criminals are the dark! They don't like the light of exposure!
As stated above, a criminal will do what is less obvious, and that has become cutting into the fill spout or worse.

The solution of course is the French's past practice of lopping off the thieves hand!!! But alas, it is best to live and not worry!!!
 
I think fuel theft by syphoning is a thing of the past because most vehicles have a ball in the fuel filler hose that prevents any hose from being inserted.
I can't remember the last time anyone actually had fuel stolen from their vehicle.
 
Siphoning gas from a car, with the balls/coiled wires or other antisiphon devices installed and tanks that only hold 20 or fewer gallons is not what worries me.

What worries me is having tanks with large and simple 3”+ openings that hold 120+ gallons. No filler tubes to have to finagle.
Easy for someone to steal $500 worth of fuel in just minutes, or insert foreign liquids.
Diesel theft from large tanks and stations is very real and still happening.

WE do not have locking fuel caps it would require two caps and keys and I would rather have them get the fuel then damage something trying to get it.
 
Another story
 
I have never used a locking cap on any vehicle. I do not see the need to start now. Been driving since ‘74 and never had a problem.
 
With most modern vehicles having locking fuel doors, check valves , etc, gasoline thefts are not as easy as they were in the 60s and 70s. Unfortunately todays theft just punch a hole in the tank and drain it into a pan. Larger security issue.

If you ask an urban UHaul dealer with a lot About fuel theft. Most have suffered a loss due to theft.

However interesting comments here.

Honestly I haven’t thought much about this topic since 1970s living in the Northeast However with $5 diesel and 100gals sitting in a tank with ready access, gives me pause.

Maybe we follow the urban California residents lead, just leave the doors open, windows open so the thieves don’t break the door/windows to rummage through your stuff. :-)

Yup. What the chain stores do: Just let the shoplifters take what they want without consequence. Emboldens them for the next hit. Fun!
 
Just leave a 5 gallon can of fuel next to the truck. 😂😂😂
