So I like to know how well my fuel system is working so I want to install a Externally adjustable FPR with a gauge BUT I have looked over the whole fuel rail and lines and I cannot find the FPR or a vacuum line to support it. Drivers side is two black dampners (no vacuum line) one on incoming and one out going and I followed the hardlined everywhere and NO FPR!!! Am I crazy? I also looked at the intake manifold and fuel rails off the JDM engine just for a reference and it doesnt have one either but it probably is on the firewall so I dont know. Any help much appreciated.
