Fuel leak @ Pressure regulator... HELP!
Having a hell of a time trying to get my fuel rail/fuel lines to stop leaking. Here is whats happening;
Ive got my fuel rail + injectors all hooked up, new o rings, and when I pressurize the system (turn the key, fuel pump turn on and builds pressure) anywhere after 30psi it starts to leak at the hard like that goes into my fuel pressure regulator.
Over the past 3 days I've been at it non stop trying all different size orings, hooking it up in and out of the car, tried doubling up o rings, using sealant, you name it. Nothing I've tried seems to work. I've been to every parts store in town, including hardware stores, and no one has any suggestions I haven't tried.
The bracket that holds in in doesn't seem to be doing much, with everything tight I can still wiggle the line a bit. Wondering if that is normal? Any advice is appreciated!

Are you using the correct o-rings?
