Will any of the aem fpr's bolt onto the aem rail for our cars? The end of the rail has a strange 2 oring and 2 pin setup for a stock regulator to bolt to. If i need to use a universal with it, i'll just use a modified stock rail i have with -an fittings tapped into it.
 
It should already to tapped for AN fitting on the ends. But yes you can use the bolt on universal AEM FPR. And yes they are a retarded design.
 
the aem rail is the biggest piece of garbage made for our cars. stay away from it!!!

If I remember correctly, the inside diameter of the AEM fuel rail is not much larger than our stock fuel rails. Just tap and install some an fittings to the stock and your good to go. Currently using that setup on my 1g, last dyno was around 610hp.
 
How ironic! I was looking to spend $5 on a set of 550's.
