2002 Buick Century Custom 3.1L Fuel Leak Sign In

I recently tried to replace my injectors, now the fuel seems to be leaking in two different spots. At one of the injectors, and also I think it is leaking from this circle thing attached to the fuel line.

I have attached pictures.

Thanks for any help.

Did you put new o wrings on the injectors when you repaced them because with how many miles your car has you need new ones. Also make sure when you put the new ones on you put a little gas on them before you slide them in. If you still need help search reference removed

We don't refer people to that moron

Look out, Kilmer is bad name around

If that fuel pressure damper is leaking, you're going to need another fuel rail. You have to be extremely careful when removing the injector rail. The o rings like to stick, so you need to pry up on the rail carefully while popping the injectors out of their ports. If you pry in the wrong spot or twist on that fitting, you can damage the rail.

You need to put a little mineral oil on the top and bottom injector o rings when you pop the injectors in. No lube and you can rip the o ring installing the injector.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
