jerryb Posted June 27, 2006 Share Posted June 27, 2006 Why are there two on the RB20?? I have an adjustable NISMO regulator to replace the orginal. But which one do I replace? Quote Link to comment Share on other sites More sharing options...
jerryb Posted June 27, 2006 Author Share Posted June 27, 2006 Come on guys...somebody must have a bit of info on this?? As near as I can tell the actual regulator should be the second unit...after the injectors but why is there one before the injectors.

cheftrd Posted June 29, 2006 Share Posted June 29, 2006 The first one is a damper. The pressure regulator is the one on the front of the fuel rail. Quote Link to comment Share on other sites More sharing options...
jerryb Posted June 29, 2006 Author Share Posted June 29, 2006 thanx!....a damper for fuel pump variation? Is this required or a NISSAN safeguard? Quote Link to comment Share on other sites More sharing options...
