Fuel pressure regulator vacuum line & PCV Valve Grommet
Hey guys, I have a two part question:
1. does anybody know where I can get a longer fuel pressure regulator vacuum line? I have a Trick Flow manifold and it seems if I go with an Aeromotive FPR, the vacuum line will be too short. Worst case I go with a BBK, but red would go better with my motor.
2. Does anybody know of a PCV valve grommet that ACTUALLY FITS a Trick Flow Track Heat intake manifold? I tried three different brands and they are either too tight or too loose. The one I have in their now you can yank in and out with little effort. I was doing a boost leak test to check for vacuum leaks and I cannot build more than 4 PSI because all the air goes straight out of the PCV valve grommet.

I made my own vacuum line for the FPR. Had some left over nylon hose, from the vacuum/boost gauge I bought, and put a couple ends on it. You can make it however long you need to. I ran it off it's own vacuum port on the intake, so it has dedicated vacuum.
I also had the same issue with the PCV grommet. I tried a few different ones, and none fit well on my lower intake. I ended up using black RTV to get a good seal. I just hope I don't need to remove it.

They way it's looking I'm going to have to use the RTV. A method I would like to avoid if possible, but sometimes you do what you have to do. I can't get past 5 psi and that's a problem. The pressure at 5psi shot the PCV valve & grommet out like a blow dart gun.

So I called Trick Flow and asked them what brand might fit. They said OEM Ford if you can find it, and that's about it. I called my local Ford dealer and asked them to get me one. They will have it tomorrow. If the Ford one does not work, I'm using the RTV method.

I couldn't use a BBK regulator with my TrackHeat intake on the stock fuel rails. The OD was too big and hit the upper intake. I ended up using a Holley adjustable regulator which is the same size as the OEM unit.
The PCV valve should shut off under boost, should it not? Perhaps you need a better valve. Besides, the boost should stay in the cylinders, not the crankcase.
