Locking gas cap

While working under our previous motorhome I noticed a "boiler plug", basically a large self-taping screw with a neoprene washer, screwed into the bottom of the tank. Since the rest of tank was in good condition, I suspect the 75 gallon tank had been drilled to steal the fuel at some point before I bought it. Some years later that plug was useful though, when I needed to drain the tank and lower it for a fuel pump replacement.

Well there’s a silver lining to the tweaker epidemic!
Maybe I should go drill my tanks in the right spots so they don’t screw it up? Nah, they’d drill right next to it.
With fuel prices, diesel will become more of a commodity for thieves. Til now, it was mostly just homeless addicts, who generally don’t drive diesels. We’ve had a lot of gas stolen. Diesel in a slip tank just turned into an environmental cleanup when the tweakers busted the lock off of that pump and then pumped a bunch on the ground. Probably hoping it would turn to gasoline at some point…

HaHa my 2021 F-150 doesn't have a cap either. But, it's to hard to put a hose into the tank to get gas out.

In my area I'm more afraid of solen catalytic converters. The new truck is warrente and I'm afraid of modifying it to slow down the converter thieves.

The locking gas caps are mostly just for piece of mind. I had a used Jeep Wrangler I bought as a daily driver that came with one but no key. It was locked but a key wasn't needed. Just firmly squeeze the edges of the gas cap together while turning and it spins right off. Squeezing the edges together keeps the outer shell from turning freely when locked so you can still take the cap off.

Which cost less a tank full of fuel or new tank? I choose not to require them to rupture my tanks.

My RV's gas filler is recessed. I bought a universal "door" and put it over the opening and added a micro switch tied to the alarm. When armed, it works the same as someone opening a door. The only issue (didn't think of this when doing the initial install so had to redo it) I need to hold the fuel nozzle at an angle so I ended up having to orient the hinge at the top. The door doesn't have a lock as I use a locking gas cap. The purpose is to get any thief to open that door to trigger the alarm.

I had a lock cap for a truck once and lost the key. Did a little research and learned they are designed to easily bypass the lock with a simple tap with a hammer and screwdriver.

They sometimes cut the filler tube. DAMHIK.

For over twenty years now including camping, hiking, fishing in remote areas and parking in big cities such as SFO never a problem with my three trucks. I love my locking gas caps and two prong steering wheel locks that are highly visible from the outside. Whatever floats your boat then do it. TTB SAB
