Message	I have quick question about injector o-rings. I searched with no luck. I replaced a set of injectors on my DD, but am now getting fuel leaking down out of my fuel system. My question is this; how does a leaky injector o-ring cause fuel to get into the engine? If it leaked from the fuel rail side it would leak down the injector, it it leaked from the manifold side it should suck air, not extra fuel. So why is my fuel pressure leaking down, when I smell no raw fuel smell in the engine bay? Thanks for the time and I appreciate any input. -Eric
