What type of thread is the Schrader valve/FP test port
Is it a normal AN thread or is it some odd ball?
I am putting a new motor together and I am using a Holley Stealth Ram just trying to figure out how I am going to run my nitrous fuel supply line with the holley fuel rail.

It's 4AN unless you take the fitting off, not sure what that would be; should have a 4an fitting on it though. Mine's running my nitrous via 4an.

Are you talking about the port on the front of the fuel rails where the heater hose on the Throttle Body would go? If so, removing that schrader valve will give you the same threads as a fuel pressure gauge, 1/8 NPT. I just put a fuel pressure gauge on my HSR this week. Maybe I'm answering the wrong question though?

I am asking about the adapter on the stock fuel rails. I was thinking about removing the plug on the HSR fuel fails and put an adapter in there, but I didn't know what kind of adapter I needed. The shrader valve on the Holley rails is rather small thats why I was thinking of removing the plug and going that route.

Going off the end of the rail would probably be the best route to ensure full flow. Coming off the rear rail by the FPR would do it.
The 1/8" could be restrictive at the wrong time.

I still need to build the bottom end, but I hope to have have it done by summer...we'll see.
