This is my truck. I did the insert thing but had both pictures up.

Just noticed this ad on Ebay. Looks like the same picture of my truck.

Anyway, if you don't have one of these...Why?

Nice, I like the magnet. I'm sure in time others will catch on and there will be more.
Mine was $2.00 from Home Depot. Go to the plumbing section and get a 1.5" rubber cap. Might need trimming but works great!
Now a reminder - I HAVE NOTHING TO DO WITH THE SALE OF THESE THINGS!

I bought mine for $35 from some guy who was selling them on another forum. In my opinion it is a great product. Also agree it's expensive. Quality is "job one" and I'm proud to have one.

I see people proudly spending literally thousands on throwing away the factory tires to replace free tires with others, hundreds to illegally tint their windows, painting and adding decorations to their trucks with no real practical value.

Mine seals off the top of the open fuel cap above the second flap. It will keep rain and dirt out of the fuel tank. That's practical and this is a "neat quality" item. No idea if that ad on Ebay is selling the quality model I have but it looks like it.

If I remember close to right, when they came up for sale maybe 30 or more of us bought them eagerly. All feedback was positive and we were satisfied.

I don't feel "there's a sucker born every minute". This thing works and corrects a problem with a measure of class.

I've read in other online sources that there is no need for an actual fuel cap. In fact, when the dealers prep the vehicles they're supposed to take OUT the green plastic insert on the fuel neck.

My truck came w/ that plastic insert cap and I'll just simply keep it there. I don't see how it can hurt.....

well sure, but most failsafes don't need to be there either. Just a trick little piece of mind IMO...
You should see how much dirt is in the fuel filler area even with the fuel door gasket!
I have one too, if it saves soot from getting into the fuel it is worth it. Makes my brother in his 6.7L Powerstroke wish he had one.
Nothing has been found in his fuel no. But when you look underneath the fuel doors and see dust and dirt, a little extra protection isn't bad. Plus, if I let someone borrow my truck it is just another fail safe to ensure they done out gasoline in it.

Never thought of some jerk putting gasoline in it. Possible and it is a reminder.

If you take your finger and push down that upper flap you will see a second flapper. On top of that there is usually a puddle of fuel from hose drippings while pulling out the fuel nozzle.

Exposed to air, that fuel will deteriorate. Granted it's not much but it is some. Dirt and water will obviously get on the top flap from anything passing into the fuel door compartment. It's not really a sealed area. With the cap sealing the top of the filler tube the problem is GONE.

The EcoDiesel I just played with had a small green plastic cap that you slip in.
My cap just arrived. Probably 4 weeks before my truck.
I use the little green plug that mine came with for now, but I will buy a better one, maybe like the green magnetic one soon. Just a little extra piece of mind when washing and stuff..
If you can't spoil your truck, who/what can you spoil (besides your dog)? Bought my custom fuel cap before the truck was even delivered!

(Who got into "trouble" from the wife for sitting in my Laramie ED in the driveway when she came home from work this evening. Apparently she was not happy with the fun I was having as I was figuring out the nuances of the media player while drinking a beer. Of course, had to have the sound sound cranked up. Guess she's going to have to get an ED so she can have fun, too!)
