Review on 1 Piece 90 Degree AN4 4AN AN-4 Female To AN4 4AN AN-4 Female Swivel Fitting Adapter For Oil/Fuel/Water/Fluid/Air Line/Gauges/Hose Tube (90 Degree, 1 Pieces) by William Nunes

I recently purchased the 1 Piece 90 Degree AN4 Fitting Adapter for my car's fuel line. Although it arrived promptly, I was disappointed to find that the quality of the adapter was only average. The finish was not as smooth as I had hoped, and I noticed some imperfections in the threading. Installation was not too difficult, but I did encounter some trouble getting a secure seal with the provided washers. Additionally, the swivel joint feels somewhat unstable and wobbly once the adapter is installed. On the positive side, the adapter does allow for easy positioning of the fuel line, and overall it seems to be holding up okay despite my initial concerns about the quality. In terms of customer service, the seller did respond to my inquiries in a timely manner, but I was disappointed to learn that there was no warranty or return policy in place. Overall, while the 1 Piece 90 Degree AN4 Fitting Adapter does get the job done, I would recommend searching for a higher quality option if you are looking for a more reliable and long-lasting solution.
