## Customer Reviews

### ⭐⭐⭐⭐⭐ A quality product
*by T***T on September 25, 2022*

It has the counterbore necessary to accommodate the tube end extending beyond the O-ring on the male connector on a GM fuel line; however, the counterbore diameter of 0.415" is large compared to the 0.358" version that I got from NAPA. As the O-ring gets axially compressed, and there needs to be a mechanism to limit its compression, other than by limiting the tightening torque. This mechanism is the bottoming of the tube end in the counterbore of limited depth: this depth is greater than the one in the NAPA part, 0.176" compared to 0.135"; at a later time, I will compare these with GM's own design, the next time I take such a connection apart on my 1989 Chevy Astro; I will then also measure the dimensions of the fuel filter's counterbore, if any.My first hard-anodized aluminum alloy fitting: very lightweight, compared to brass, yet as strong. I also bought the fitting that mates with it perfectly from the same manufacturer, which is also available from Edelbrock (P/N 648060) on Amazon.

### ⭐⭐⭐⭐⭐ Fits perfectly
*by J***R on March 14, 2019*

I bought 2 cause I thought both lines needed it since I was doing a LS swap from a factory tbi motor. One fit perfectly but the second line did not. I learned later on the return line is a different size. Other than that it worked perfectly.no leaks was able to convert gas lines to an6 fitting

### ⭐⭐⭐⭐ Misleading Description
*by S***S on July 28, 2023*

At the time of sale, the description said Edelbrock. This is not Edelbrock. It's Russel branded which is an Edelbrock company
