I’m new to this site and I apologize now because I’m sure this has been asked before but I can’t find a definitive answer for my question.
I have a B16a Sir II engine in my 98’ civic ex coupe.
which AEM fuel rail fits a B16a? I only see fitment selection for a b16a2 or b16a3 but I’m not sure that this is the same for a B16a engine.
thank you in advance.

 

You can use EITHER one... the difference is the type of fuel pressure regulator on the OE application. To make things easy on yourself, check the following. If the fuel opening on your B16A regulator is centered between the two bolt holes, then get the B16A3 rail. If the fuel opening is offset slightly above the center line between the bolt holes, then you will need the B16A2 rail. If you get it wrong, you will have to get another fuel pressure regulator that matches the fuel rail.

 

Okay thank you, I’m buying an AEM fuel rail and AEM fuel pressure regulator at the same time to put on my b16A.
