Works WAY better than the plastic comparisons. Very thin walls, to get it in the tight space easier than the plastic ones.

Worked perfect

This tool is a must have for anyone interested in working on fuel injection systems . I used it on my 2001 Silverado to release the high pressure fuel lines from the fuel rail 👍👍👍This tool has two different sizes that are most commonly used.

Honestly, it's the same as everyone else's. You clamp it around the line, push it in the fitting, push and pull the fitting, and it comes apart. It's made out of some nondescript metal (heavier than aluminum, not steel—it doesn't rust/is not magnetic, probably some sort of zinc pot metal).If you're looking for some high-quality tool... this isn't it, it's cheap, nothing special, but it works.
