I recently installed a victor x manifold and aem fuel rail. As I've seen is common the aem fpr does not easily fit with that combo so I switched to a aem universal fpr. The question I have is how do you plug the small port on top of rail where the fpr mounts directly to rail. I have been to all the parts stores and hardware stores and can't find anything that will thread in.

 

Tap in and plug it with a bolt
