GMC Posted February 10, 2011 Share Posted February 10, 2011 Hi all, Finalising the rebuild of my 1992 C20XE for my Manta at the moment. The donor engine had covered 100k, so as part of the rebuild I intend to have the injectors cleaned or replaced. It currently has yellow injectors..........should I 1. Get new yellow injectors? 2. Get reconditioned yellow injectors? 3. Get blue injectors - I see these for sale as an upgrade? What's the difference and is it worth cjanging to blues? Thanks, GMC Quote Link to comment Share on other sites More sharing options...
GMC Posted February 10, 2011 Author Share Posted February 10, 2011 Woops, Might be beige.....not yellow!!! Same questions apply please Quote Link to comment Share on other sites More sharing options...
garymanc Posted February 10, 2011 Share Posted February 10, 2011 the beige ones are for 2.5 bar fuel pressure regulator and the blues are for the 3.0 bar fuel pressure regulator. saying that i have the blues on a 2.5 bar fuel pressure regulator as the spray pattern is supposed to be better but if i used the 3.0 bar if would overfuel.
