Hi, I have the AEM # 25-104C ,(H22A1) fuelrail and I want to use "AN to Metric adapters" for the side threaded ports for fuel inlet and outlet.

Does anyone know what the correct thread is in the fuelrail?

Thanks.

 

The ends of the rail are tapped with a 9/16-18 thread. Standard, not metric. -6 and -8 port fittings are readily available in 9/16-18.

thnx for the reply, I was wrong about the metric fittings, it is -6AN both sides.

Thanks again.
