EN-49248 Injector Rail Assembly Remover Tool Direct Injection Tool 6706 For 2007-2014 GM Pontiac, Saturn, Cadillac, Chevrolet Direct Injection Engines V6 & 4 Cylinder

I was prepared for this to break or be junk after one use. I had a rail that I had been soaking and prying on for days with no luck what so ever. I took my time installing the pullers, hand tightening really good and then prying a bit with bars and right off the bat they started to come out, I slowing worked down the line by hop scotching one puller at a time and prying had the rail out in 20 mins. Wish I would have had it days ago. 4 pullers would save a tiny bit of time so not sure if its worth have 2 sets as some suggest.

Tried on GM 5.3. Could only use 3 out of 4 as one of the tools had been tapped with the wrong thread pitch during manufacturing. The tool is not very stable and has a tendency to flex as you put tension on it so I didn't feel comfortable doing the job without the support of a prybar to do the heavy lifting while I used these tools to take up the slack as I worked the fuel rail up little by little. Decided not to keep for future use, I'll just spend more on a better set next time I do this job

I bought two sets as recommended to pull the injector rails from a Silverado 5.3L engine. They worked but by the time I was finished with the second rail, the mounting bolts and hooks were all bent out of shape. The body of the tool itself started coming apart so I doubt if they could be used again without totally breaking. I hate to do it because I wanted them for my tool collection, but I'm sending them back.

Works wonders, safe so much frustration and time! Took hours without this tool previously and around 5 minutes with it.

Se doblaron , a última hora usamos otra herramienta hecha en el taller , pudiera servir si no estuviera tan pegado el riel de inyección
