Locking Fuel Cap??

I have a locking gas cap that fits my 2015 truck. Correct me if I'm wrong but wouldn't it be more cost effective to protect the fuel vrs. the def? Contaminated fuel is very expnsive but contaminated def would mean replacement of the catalytic converter. Am I over simplifying this or not understanding the complete system?

Contaminated fuel could cost you a complete fuel injection system replacement of many thousands of dollars ($8k to $10k). Contaminated DEF throws a CEL and will require the tank to be emptied and cleaned, then refilled with good DEF. I would be more concerned about my fuel.

That's pretty much what I thought. Just wasn't sure if bad def could take out the cat? Thanks for the quick reply.

Bought a locking gas cap for my 2011, moved it to my 2015 no problems, I just like the added insurance that no one else can but anything but diesel in the tank but me.

I also moved the locking cap from my 2012 to my 2015. The locking DEF caps should be available right after the first of the year. I will order one of them once they are available to keep both systems safe from scum.

Just out of curiosity, where do you guys live that you need to worry about people putting water in your fuel tanks? In my 38 short years on this earth I have never known of anybody having had water deliberately put into their fuel tanks.

Don't recall anyone specifically saying water, but any foreign substance. Also just stealing fuel. For an 18,000 buck system whats 5 or 10 bucks of insurance?

Simple answer would be to put a lock on the trucks fuel fill door. You can either order the door as an aftermarket item or put a cam style lock on your current door. There is a pretty good write up on the forum here somewhere on how to do it.

Could you guys post a link where to buy the locking fuel cap(s) you're using for the 2011-2015?

Thanks much.

Doesn't have to be a bad neighborhood. It could be what someone would consider a prank. Many years ago, my neighbor had his gas tank filled with sugar by some punk kid. Just a few years ago, my yard was wrapped as a prank because my son was a teenager who broke a girl's heart. What's to stop someone from messing with your tank? Additionally, someone who sees a nice truck in the driveway and gets jealous (or a Ram owner who wants to exploit the "issues" with the CP4 pump to prove a point), may decide to take out his frustrations on you in the form of a half gallon of water. It doesn't have to be a high crime area to feel better about extra protection from contaminants introduced intentionally. Nothing wrong with adding a locking cap or door if it helps you sleep better. There are a few jerks out there.

For me it is simple, in Oregon it is State mandated that all fuel stations have attendants that fuel the vehicles. The locking cap stops these folks from starting to fill with gas an also stops anyone that might conisder putting anything in the tank from causing me a problem, or stealing fuel. It is a peace of mind thing, I don't live in a bad area, but you just never know.....
I had a friend that had his kids put pea gravel in his tank.....

Mine is a Stant # 10510D that fits both the 12 and the 15.

Hey Pat, I've heard from a few forum members that their state requires attendants to pump their fuel. What is the reasoning for that, or what excuses do they offer for that requirement? I always preferred to do my own - even back in the days when you could choose between a full service island and a self service island. It was never about the additional cost of the full service, but about trust for what you got.

Doug,
I think it is Oregon and New Jersey that require it. They say it is more environmentally sound since they are trained to not top off, and that it creates jobs. The good thing is that there is an unwritten rule that Diesel owners can pump their own, so I have always pumped my own. It is crazy, but what can you do.....

It's funny that they think am attendant making minimum wage will be more careful not to spill your fuel than the person paying for it. Also funny to me that we still sample all of our ports (up to five) on an airplane looking for water or contaminants, and dump every one onto the tarmac without question. Sounds like someone's idea of creating jobs that aren't necessary - maybe like elevator attendants to push the buttons that every kid in America wants to push for free?
