Jabba23 Posted March 27, 2013 Share Posted March 27, 2013 hi i need to fix my FPR and i was considering uprating it to a 4 bar one to improve the performance, seeing as i'm gonna be in the region, any thoughts, it's 30 squid for the new regulator valve on it's tod as opposed to a tenner for the gasket/ seal set or 120 for the whole shebang Quote Link to comment Share on other sites More sharing options...
RedLineMike Posted March 28, 2013 Share Posted March 28, 2013 of the top of my head im sure the standard regulator is 4 bar anyway Quote Link to comment Share on other sites More sharing options...
chrisbowler Posted March 28, 2013 Share Posted March 28, 2013 I assume we are talking TD5??? The pump in the tank pumps to 4 bar. The regulator controls this as required to maintain the pressure as demand constantly changes. As Mike has said - the standard system is 4 bar. What advantage is a higher DELIVERY pressure in a common rail system, when it is the injector that creates the high pressures needed. Never heard of a TD5 running out of fuel in the gallery if the pump is in good condition. Chris Bowler Quote Link to comment Share on other sites More sharing options...
