Its like one headache after another these days. My tundra has been down for a while now because of the dreaded pink milkshake. I took the opportunity to do a number of maintenance items. One of which was replacing my starter because it was starting to act stupid. So in order to do so you have to pull the intake manifold and in turn the fuel rails. I bought all new o-rings and the reinstall went rather well....so I thought. I finally got to the point where I was ready to fire up my truck again to flush out the transmission. It turned right over which was awesome.....but the first injector on the passenger side (first as in if your looking at the rail its the furthest on the right) is just pissing fuel all over the place. Never had this problem before. I had a spare injector that I swapped in with the same results (using a different o-ring). Anyone have any ideas what the hell the problem is or what i can possible look at? I took the rail off in order to swap out the injector and everything looks fine. Its tough to track the leak because by the time you get the rail off the gas has already evaporated....plus you lose a bunch of fuel pulling the rail anyways. When I go to put the rail back together and back onto the intake manifold, I press each of the injectors into the rail and then line up the bottom of the injectors with the ports in the manifold and then push everything into place and bolt down.....am I doing it right? I mean i dont have any issues on the drivers side and the other three injectors are fine....even after pulling them all and putting them back on when I swapped the injector out. I'm lost.....and ultimately this is holding up the entire process of getting that tranny flushed and my truck back on the road.

I have not worked on the fuel rail or injectors on a 4.7, but could it possibly be an o-ring from when you pulled out the injectors stuck in the port? Long shot and just thinking out loud.
