Diesel filler neck adapter

So during the holidays we are driving our diesel Gladiator home from Tennessee and we stopped to fuel up at an Exxon off the interstate. It was the only station at the exit. When I went to put the nozzle in it would not deactivate the door or flap that is installed on the Gladiator. I was pretty tired from driving all day so at first I thought the issue was just ‘Operator Headspace and Timing’. My first inclination was to force it in, however I did not want to break the Jeep so I went to another pump thinking there was something wrong with the nozzle- same deal on two different pumps. We ended driving down the road to another station. Luckily I still had over a 1/4 tank so it was no big deal.

It turns out the Jeep has a ‘Dummy Door’ that prevents a gasoline sized smaller nozzle from being inserted into a diesel fuel neck. This station had the same sized nozzle on all pumps- small. 🤬

Many of you probably already know this, however new to me was the fact that there are three different sizes of fuel nozzle. Small- which is for gasoline, medium- which is for passenger car diesel and then large nozzle (that’s what she said!) which is for big rig diesels. In addition there are different sizes fuel nozzles for the various fuel cans we all carry.

With all of this in mind I bought a ‘Diesel Fueling Adapter’ from VW/Audi. It was $16-ish and works very well. It comes in a nice container so you can store inside the vehicle without a mess.

Eventually I’ll see if I can remove the ‘Dummy Door’, but until then this will work for those rare occasions that there is an issue.

If anyone has a better solution to this please post up.

For those that have the diesel. How have you dealt with the DEF consumption or has it not been as bad for you guys as some of the reviews have said?

Check under the rear seat. Mine came with one next to the jack.

Like the kid on ‘South Park’ says: “I learned something today”.

This is one of the many things I really like about this website, the sharing of info.

There is the funnel/adapter for diesel fueling that comes in the Gladiator. I dug around and ours was in the glovebox.

See below.

Our last trip was about 1300 miles and we went from 100% to 70% on the DEF tank. My government school math says that’s about 1.5 gallons of the 5.1 gallon tank. I did about 70-80 mph for most of that distance. I can live with that for now.

What does it take to do an EGR delete on this engine? Asking for a friend.

Appreciate the feedback. Hoping to get at least 3000 or so out of each tank full.

My wife's yukon (gas powered) came with one of those so you can fill with a gas can... If you try to use a gas can without it, it burns your urethra
