Ok so i just swapped a jdm b16a into my 99civic ex. now when i hook up the fuel line to the fuel rail and go to start it, it leaks fuel. now i went to honda and bought the little washers that go in between the fuel line and rail, i put those in and go to start my car and it still leaks gas. now i dont know if there is a difference between OBD1 fuel rails and OBD2 fuel rails?? or if there is a crack in the fuel rail itself. does anybody have any suggestions on what i should do?

 

Well is the leak going down the injector or coming from an odd spot in the fuel rail? If its going down the injector, take out all your injectors once again, check to see if there are any rips in the O-Rings, any small peices missing, hell, anything that looks like it MIGHT cause a problem. If you need to replace an Injector O-Ring because you ripped it, when you go to put them back on, make sure you dab some engine oil around the O-Ring, it wont hurt it or the injector and it makes it slide in very easy and helps to prevent from ripping an O-Ring.

If its not the O-Ring, you may have a crack in your fuel rail, which I highly doubt. I've had a fuel rail with a casting problem in the past an its EXTREMELY rare but will typically shoot out an insane amount of fuel. If your Fuel rail were cracked, normally it would just snap it in half instead of cracking a small peice.

I think you keep ripping the O-Rings though, it's very easy to do. Don't tighten ANY bolts down until the injectors are fully seated.
