Nope but did it and replaced them all @ After you unbolt the file rail you sort of lift it straight up and rock it slightly form end to end and the injectors come out of the holles Lift it up a bit and aside and you can see the U shaped retainer clips that hold them on the rail - you have to get a little pick inside the side and pull it out a bit - like a dental explorer if you know what they look like
once the clips away from the back they come off like a staple but be careful cause if they flip away - good luck finding them.
I had to save the o-rings off the stock injector and good thing - they are very expensive for rubber circle s- like over a buck something each..
