Fuel Leak!

Based on the photo, any guesses what exactly is the source of this leak?

I replaced all the injector o-rings and the the two short hoses back in February when I removed the intake manifold to fix the 'hose mess'.

Any guesses what's causing this leak? There's a pool of gas just to the right of injector #3.

Could be all the stuff you mentioned. Most likely where the injector meets the fuel rail. Connect all the hoses injectors etc and cycle the ignition key on and off a few times WITHOUT starting the engine. The fuel pump will cycle on and off enough to prime the system. The leak should reveal itself.

injector o rings

except he just replaced those. what makes you think they're bad again? are the injectors all properly seated in the rail and manifold?

[BraveUlysses]

They seemed hard enough to remove. I had only replaced the o-rings where the injector connects to the fuel rail, not the ones at the tip of the injector.

I had the injectors cleaned by a specialist who replaced those o-rings, so we'll see if this fixes everything up.

Look over the rail itself for any cracks? like where the lines go into it.

I had a leak in the same spot one time ended up being a cracked injector.
I think I broke it taking intake manifold apart previously. I ended replacing all the injectors, hoses and rail.
You said yours were checked so hopefully there good.
Good luck

Definitely a cracked fuel rail :(

Fucking hell.

Buddy hooked me up with a fuel rail, no leak @ the rail anymore, but now it's pissing fuel like no tomorrow at the inlet to the fuel filter. The filter is 5 months old and I replaced the hose going into it (new clamps too) and its still pissing gas.
