I just did this mod as well. I did a slightly different method, instead of using the plastic T's I used the rubber ones made for vacuum line, I think they were 7/64th or something like that. I simply cut the line the the frps right where I wanted the T and left the original line on the solenoid and put it on the other side of the T. It fit very snug and I have not glued or zip tied anything and have no problems. Its a little easier than using the zip tie.
