Review: Return line fitting - So by accident I bought 2 of the other size thinking both tbi lines are the same size. I was wrong, they screwed on perfectly to the return line, not the main fuel line. Either way It's exactly what I needed for my swap. Convert the line to a an6
Review: The correct fitting - The fitting is just what I was looking for. It was the final piece to complete the fuel system.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Return line fitting
*by J***R on March 14, 2019*

So by accident I bought 2 of the other size thinking both tbi lines are the same size. I was wrong, they screwed on perfectly to the return line, not the main fuel line. Either way It's exactly what I needed for my swap. Convert the line to a an6

### ⭐⭐⭐⭐⭐ The correct fitting
*by M***L on June 21, 2022*

The fitting is just what I was looking for. It was the final piece to complete the fuel system.

### ⭐⭐⭐⭐⭐ Not for inverted flare fittings
*by M***E on October 1, 2015*

This fitting is does not have the cone at the bottom of the M14-1.5 female to seal with an inverted flare fitting. It might seal but I doubt it since an inverted flared tube is made to seal against that cone feature.
