Recieved product...
I'm looking forward to using the product. Its bit pricey for something that seems pretty simple. This has been delivered to my mailbox at my residence. I wish Amazon WOULD NOT LEAVE MY PACKAGES IN MY MAILBOX. I WOULD PREFER MY PACKAGES BE LEFT ON MY PORCH BY THE FRONT DOOR. I believe this to be laziness on the part of the driver. Putting packages in my mailbox leaves no room for my mail....thank you

Worked like a champ!
I drive a 2016 Kenworth T680, driver side tank cap was barely holding on and leaking fuel due to threading. Kenworth told me I had to replace the entire tank for over $700.... Bought this instead, easy to install, no more leaks. Now I'm gonna buy another for the other tank to match.

Worth the money
Love these, no more leaks. They are beefy, with 1/4" O-rings on both the adapters and caps. They're huge, easy to grip, monster threads with fewer turns to tighten. One of the best aftermarket accessories I've ever bought for my K Whopper. You won't be sorry with these bad boys on your tanks.

Leak defender is the only solution
This is the second one I’ve bought is the only thing I could find that would stop my gas tank from leaking. It’s not even up for dispute. And it looks great.

Money Money Money in my tank not on the ground!!
It's definitely worth the investment. My old fuel cap was farely new about 1yr old. But last week it stopped gripping the tank. I parked a trailer and looked down in the front of the truck there was a trail of fuel. Money on the ground. As an owner operator every penny counts. I thought I would have to replace the tank. After doing a little research I found this. I was hoping to find a cheaper fix but this adapter works perfectly.
