I gave this product 4/5 stars for 2 reasons. It should come with instructions. It wasn’t hard to figure out but not everyone is a mechanic so some people need instructions. Second reason is, it needs another 90 degree instead of straight nipple. Overall great quality and fast shipping.

It’s pretty good 8/10

It’s a good kit, but honestly needs another 90 degree fitting. It works fine with out it but it would be easier with it. Also I wish the 90 fitting came in black like other kits. It’s a good price, great quality and value. The only bummer is no instructions :( Kinda takes awhile to install. #1317815
Cat Fuel Filter Adapter

Product is good quality all around. Only a 4 star rating because it did not come with instructions and when I called customer service I was told to watch a YouTube video of someone else installing of which there were no videos of this product. Then I was told they are all the same but after much research, many have different fittings and tubing so they are not the same. If it wasn't for that I would have gave 5 star.
