Review on OTC 5060 Detroit Diesel Injector Socket: Ideal for GM 6.2L and 6.5L Diesel Engines by Ronald Noel

Perfect size, thin enough to fit between the injector and the casting in the head. The ability to use a socket wrench or an open-end or open-end wrench helps a lot in tight spaces. I gave it 4 stars instead of 5 just because it feels like it should be a bit tighter around the jets. I had to screw the injector back into the head a few turns only to loosen the bushing with a few wiggles because it was too tight to get out by hand. I don't know them all, but mine could be a little smaller to fit. In general, it turned out for what I needed it.
