## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked exactly as expected!
*by A***R on February 8, 2020*

I was a bit worried about buying these o-rings based on some of the reviews. But I decided to go for it and give it a try. I had to use a dental pick to get the old o-ring out, and when I did, it came out in fragments. It was dried out and completely disintegrated when I removed it.I have a 2007 883XL Sportster and the new o-rings looked too small at first, but I figured I should at least try them since I had nothing to loose... I decided to lubricate the o-ring with some silicone lube I use for the o-rings in my swimming pool before installing. I am sure that a professional will tell me that is the wrong lubricant to use, but we are talking about such a small o-ring and a small surface area I figured it is probably ok. The new o-ring was a bit tricky to get into it's seat, but I was able to use a socket that fit perfectly into the check valve and that pushed the o-ring right into its seat without twisting it. I think this was also simplified because I didn't try to insert the o-ring dry. - I reconnected the fuel line, put the key in the ignition and flipped the switch to 'RUN' which pressurizes the fuel pump/line. Previously this would have _sprayed_ gasoline all over the place, but the new o-ring did the trick. Not a drop of fuel leaking from the check valve. I took the bike around the block a few times, and the assembly remained dry as a bone.So I have to give the product a good review. It worked as advertised and I really only needed 1 o-ring. So I have a pack of 4 spares to throw on the bench for the future.
