So ive searched and searched and cant seem to find the problem...
Maybe you guys/gals can give me some insight here. Ive got a fuel leak at the injector rail/injector, Im running the stock rail with (Pink Top) Evo Ix injectors that have had all new seal twice now and all new spacers/bolts. It seems to be coming from the 2nd injector from the passenger side(sorry not the correct term) It does not leak at idle or at 3000rpm when the car is sitting still but when I drive it no matter how hard it leaks and squirts it up onto the rail and creates a mess and puddles by the injectors... Specially when i get into boost it seems to make it worse so anybody have any ideas to this?

Ive come up with:
-Cracked rail
-1 or 2 injectors are bad and leaking somehow
-Leaking somewhere else???

What stumps me is it only leaks when driving and has no leak at idle or XXXXrpm and not moving
 
So you put on new o rings at the injector-to-rail connection? Did you se lubrication and ease it into the rail? Have you attempted to try switching the injectors around to verify it is the injector or the rail?
 
May be you couldve rubbed that o-ring on that injector to hard and gouged it..u dont want to twist the injector while putting them in the fuel rail it rubs down the o-rings. You could also have a crack in the fuel rail or even the injector its self. have someone rev the engine as you watch the fuel rail and injectors.
 
It has had all new upper and lower seals(used some lubricant on the install) and I am attempting to switch them around to see if maybe just 1 injector is bad(stiil searching other threads)and will report back

Id like to put the car in the air and run it up a little and see if I can find the leak since it doesnt seem to do it when the car is just sitting still at any rpm but no way of doing that other than jack stands and thats a little sketchy haha

Figured the issue out tonight....
I took all 3 sets of lower seals that I had(Old, new, and new) took them and test fitted them to the injectors 1 by 1 to see which had the tightest fit to each injector and ended up using 2 old seals but anyway put them back in and no more fuel issue! I now have some spares laying around which we all know we need spare stuff for DSM's haha
Did find another issue as I noticed the fuel was dark colored and around injector #3 there is a leka in the valve cover and it is leaking oil down giving it a dark color so that will be tackled this week since under boost it creates a mess but thank you for all the help guys!
