PD/Integrated fuel rail

PD/Integrated fuel rail
I am getting a fuel smell from my engine bay, and I know it isnt the pulsation damper, but since it looks like I have to pull up the intake in order to fix a leaking primary, I might as well fix the PD. Anyone have a PD or Fuel rail that they would want to sell? And maybe some 550 CC Injectors?

If your car is a NA; do not put in 550's! You will just run super rich and loose power. Deffinitely fix the PD while you're in there though. And as far as I know a leaking injector will not give you a fuel smell. The leak could come from where the injector goes into the rail, but when the injector leaks it just drips down into the motor where you would probably not smell it. Either way taking it all apart is probably a good idea.

I am not putting 550s in the primary, I was gonna experiment with putting them in the secondary positions! And its leaking from around the o-ring. I re-used my old ones cause I am lazy and cheap. So now I suffer the consequences. And its not a really noticeable smell, but anytime you smell gas in the engine bay, its not a good thing.

Yeah, that's what I thought you meant. Just pointing it out to some others readers who might not be aware. If you smell gas then something is wrong and should be taken care of. I bet you're kicking yourself now for not replacing those o-rings. When I had my intake off I went overboard and replaced everything that could be replaced except one set of those diffusers (those bastards are expensive); just so I would not have to take the damn thing back apart. It is more expensive but in the end, you will probably save a few bucks and alot of headaches.

Well, there are some that say it can net you up to a 25 hp increase at the high end of the band. I havent seen any proof either way, so I was gonna do some timed runs out at the 1/4 mile just to get some idea. I had a line on some for 25 bucks a peice, but I lost the email.

In fact it will definitely go the other way due to excessively rich mixtures, unless you have a fuel controller to reduce the output of these injectors. More air, with the correct amount of fuel, is what makes more power. NA injectors at 80% duty are sufficient for ~210rwhp, and I doubt you (or many others) are even near this. Replacing the PD and the injector o-rings is a very good idea though.
