I recently did some work on my 5.7 liter Hemi. I had a terrible time trying to remove the fuel line from the fuel rail. I had a good set of quick release tools and bought another to see if that would help. No matter what I did, I couldn't turn off the line. This tool allowed me to apply the necessary force to the QD tool and pull the line at the same time. After removing the pipe I looked at it and found that the inlet pipe was bent at the fuel rail. That's why I had so much trouble taking it off. If your fuel rail is in good condition and straight, you may not need this tool. As for me, I'm glad to have this tool in my toolbox and would recommend it to anyone having trouble disabling QD lines.
