Ok,while i was away i had a shop do some work to my car, and they were expensive for the most but got most of what i needed done complete decently, but it appears they ordered 11mm fuel rail, and stuck my stock inj back in there. odd enough it worked for a while, but not its shooting fuel out of the rail like a super soaker. i have a couple options. one is to throw a stock rail (rb26) back on, but i dont have one, the other is to upgrade my injectors, which i could do, since i planned on it anyway, but i didnt want to throw in my new computer yet, and tune it. my third option which i cannot confirm that it will work, is to use larger oring which i cannot verify. i did read online that some rails are made for both size inj, but i have no clue if mine is. and if it is how do i do that, i would imagine that i would remove the gromet and it goes farther in the rail ... i have no clue. i dont have access to my car since i just got back from iraq, and i am stuck on base, i honestly get like 2hour window to mess with it, and its my only transportation. any ideas to throw in before i go there ?

Can't you add an adjustable FPR (Fuel Pressure Regulator) to adjust the fuel?

Sounds like the simplest thing is getting a new stock rail. Thats what Id go for.

the issue is the size of holes you insert the injectors, and the o rings

Yeah, your not talking about the intake manifold side of the injectors right? If its the fuel rail side, since they are stock injectors, Id just get a stock rail. See if they still have yours.

I wouldn't trust an o ring to fill a .5mm gap like that, you have between 40-60psi of fuel just waiting to leak, and that could result in an engine/car fire.

OEM is plenty durable and safe and is fine for stockish HP levels so I'd KISS and get another stock rail.
