If you have a vacuum regulator and the fuel is leaking out of where the vacuum hose is, you may have a ruptured fuel pressure regulator diagphram as seen in this video below –

However, if the fuel leak where the fuel lines connect to the regulator, you may have possibly damage the rubber o-rings.
Keep us posted.
If you remove the vacuum hose off the regulator during idle or under load and it starts driping or spewing gasoline then yes, the diaphragm maybe ripped, but you’re regulator is toast. Start the car and remove the vacuum hose, and watch the fuel regulator for about 2-3 minutes to really catch and drips or spray of fuel. If you see that, then yes you’re regulator is bad.
Another way to check is with fuel pressure specs, measure the fuel pressure with the vacuum hose attached and then with it removed during idle and WOT. The PSI should jump in the fuel line when you remove the vacuum hose a specified amount. If it doesn’t then it’s probably bad.
How careful were you to remove fuel pressure in the system before you replaced the injectors? Did you drop the fuel rail (I’m assuming you’re regulator is on your fuel rail, which reminds me What year is your civic and what engine type?). Alot of things could of happened to it. Anyways I’m sure some other good souls will chime in here with some advice.

Dreamer, you beat me to the punch! lol.
Yeah what ^ he said.
Its all good! It happens to me too lol!

Its a 95 D16z6 and yes the fpr is on the fuel rail. I was really careful while putting the injectors in and I didnt drop the rail or anything. Im actually pretty scared to start the car because fuel is just gushing out of the top of the thing, its spraying all over the engine and there is a huge puddle of gas around where the throttle body connects to the engine. Its terrible LOL
I agree with DJ Devon, I’ll have to pull up the specs on your car but I know my car has the in line on the bottom.
Here’s your Fuel pressure specs
40 to 47psi with vacuum hose disconnected
[color=#000000]30 to 38psi with vacuum hose connectedokie dokie I think you have them backwards bud, once the fuel pressure exceeds 36 psi that diaphragm is pushed up and out of the way on your vehicle and the excess fuel is dumped. Which means if you plugged it in the wrong way… you’re getting 40-47psi, which will cause that fuel dump.[/color]
I agree that if you remove the vacuum line and gas is coming out. then the diaphram is bad and the fpr needs replacement. good luck and keep us posted.C8-)
Not necessarily. The diaphragm moving out of the way doesn’t mean it’s ruptured if he simply put the line in backwards. Once you have the lines reinstalled correctly and you’ve cleaned off the FPR and it’s vacuum hose…. run the car without the vacuum hose attached. If it’s not dripping, spraying or leaking after 5 minutes (put a white napkin on it to see if it is) then you’re good to keep using it.
However, you might of unintentionally ripped or torn your diaphragm witht the increase in pressure going the wrong way, even though it is designed on your Civic to prevent you from doing just that. Hopefully it’s not and all is well.

I could not have put it better myself, nice post.
