I did a boost leak check on my car yesterday up to 20 psi. I found two different leaks on the car.

One leak (biggest of the two) was on top of my Aeromotive AFPR. I tightened the nut down a tad more, but after I leak checked it again, it was still leaking a bit.

Is this normal, I would think it shouldn't be happening?

Did anyone else have this problem, and if so, what did you do to fix it?

I also have a small leak at the elbow/Tb connection, which although it's a small leak, i still believe is the cause of my crappy idle. I have changed the gaskets on the tb like 3 damn times and it keeps leaking. I also tried siliconing the crap out of it once with no gaskets at all, and another time with a small thin layer on the gasket. Anyone else got any tips? I'm about to weld a damn elbow on that bi*** if it keeps on leaking on me.
 
The Aeromotive AFPR does leak a bit through the threads. It (hopefully) shouldn't be enough to cause a problem, but I've been considering putting some thread sealant on it and then slowly screwing it in 'til I hit the correct pressure so it will seal there. I'm sure Aeromotive wouldn't recommend that though.
 
Stale thread :coy: but I just performed a leak test and also found my Aeromotive FPT to be leaking past the top adjustment screw. When I get time will test the actual FP at 20psi to see if the leak is causing a less than 1:1 fuel pressure rise w.r.t. boost.

Did the teflon tape do the trick for you?
