Easy site to navigate through, shipping was fast.

Great service

Shipping was quick and the caps were very well made.

This is my second leak defender. The first one worked out so well I ordered a second one. It does exactly what it's advertised to do. Great product!

Shipped fast

Highly recommend. Great quality of the parts and excellent service. Leak defenders helps to save a lot of fuel!!!

I ordered from the website and it was quick an painless. I also had to pay for expedited shipping, cost was reasonable and product was shipped in a very timely manor. Received it the next day

It really helped to stop the leaking and it also look visually appealing.

Great product and people selling.

Great Great Great! NO MORE LEAK!!

I've tried everything imaginable to stop my fuel tanks from leaking, but this is the only product that actually fully stopped the leak. Well worth the money spent

works great

Definitely purchase if you drive a Kenworth! We all know how Kenworth caps leak and how hard they are to get off also this product it absolutely amazing not only does it stop leaking caps but also easy to loosen the cap back off without filling like you need a hammer like oem caps.

Fast shipping great customer service

Fast shipping and great service

Fast shippping and a great product and look good on my truck

The part fit and doesn't leak, just needed it here sooner but being close to Christmas freight probably took a little longer then usual Thanks

Product fit perfectly! Highly recommend purchasing from company.

I purchased the stop leak fuel caps for my 2016 Kenworth T 800. The cap on the passenger side works great. The cap on the driver's side still leaks a little bit. I have tried tightening it more than once. They have only been on for about a week, so we will see how they last.

Great and smooth experience highly recommend
