I have the AEM fuel rail and I am going to use one of the extra ports on it for my fuel supply for the DP kit. Does anyone know what size the port is on the driver's side end of the fuel rail is? Also is it AN threaded or pipe threaded?

 

I talked to AEM, and they said that it is 9/16-18 on both end, and 1/8npt on top.

 

Is that -6 an or -8 an?

 

-6AN. I was talking to the AEM tech, and he said that even though -6AN will fit, the taper of the AN will not seal as well, and to use the port instead.

 

Thanks.
