weird question about primary fuel rail.

weird question about primary fuel rail.
I over analyze things and I was inspecting my primary fuel rails by blowing air through them and came across one difference in the two I have.
I blew through each side of the fuel rail and the side where the pulsation dampener is let no air through on one and on the other a little air bled through.
Is it supposed to be 100% sealed or how should it be?
I'm trying to decide which fuel rail to use and which one to sell and don't want to keep the wrong one.
Also there is some white chaulky looking stuff inside the fuel rail that let no air through, the other was clean inside.

I'm assuming you're blowing through the PD (inlet) side. The PD is a diaphram to smooth out pulses. When there is no pulse/pressure, it is closed so you can't blow through it.
Imagine the fuel pump pushing fuel through the lines. The job of PD is to smooth out fuel going to injectors.
If you're going to ask about aftermarket FPR, it's built into it.

Sorry just confused. I'm replacing the pulsation dampener with a banjo bolt anyways.

So its suppose to be 100% sealed? One lets a small amount of pressure through when I blow through it.

No clue, but no matter how hard I blow it barely comes out but I can hear it, but the other is 100% sealed, I'm not sure which to use.
The 100% sealed one has some white residue inside but not much at all, the one that leaks a little is clean inside.
I'm likely just going to keep both until I figure out which is better to use.
