First question is, does anyone know id the KA FPR is interchangeable with the SR one? I've read alot of mixed opinions on it, mainly people stating that if you order a Nismo unit, which is a direct replacement for the stock fuel rail, that it will bolt onto a KA motor. My question is in regards to OEM.

Second question is i've been googling for hours on end and finally came up with a post on another board that a member asked. He wanted to know what were the symptons of a FPR going bad were and one of the Moderators said to test the FPR by disconnecting it at idle. If the rpms slightly increased, then it is working. Does anyone know if this is true?
