No downtime, installs in minutes. No costly tank repair and these things seal 100% and look great!

I had seen a demonstration of the Leak Defender previously so when the fuel caps on my Kenworth started leaking and trying new gaskets failed, I knew what the fix was. These caps are great. The design, craftsmanship, and fit are top notch. No downtime, installs in minutes. No costly tank repair and these things seal 100% and look great. Thanks for a great product.

We haven't had any more issues with fuel leaking & we have saved thousands on fuel.

The Leak Defender is the best product out there! After trying many solutions and nothing working, we found your website and gave it a shot. Your gas caps are the best. We haven’t had any more issues with fuel leaking and we have saved thousands on fuel.

I could not believe how easy to install, how well they work, and how nice they look!!!

Had problems with a stripped neck on my Kenworth fuel tank. After looking for a way to fix it, I couldn’t believe the price for new necks and the costs to have tanks dropped, cleaned out, and sent off to get them welded in. On top of that price, you also have the cost of down time. 

I ordered the Leak Defender for both tanks and could not believe how easy they were to install, how well they work, and how nice they look!!!! I don’t get excited very often over a product, but these are the best. What a great company to deal with and a pleasure doing business with. Thanks guys, you saved me a lot of money and down time.

Stopped our leaking fuel cap problems!

The leak defender stopped our leaking fuel cap problem. I only wish we found out about it sooner… It has already saved us over $4,000 in fuel tank replacement costs!
