Most are only rated to 7 bar. I think he must be seeing that preasure else were. Edited 08/01/13 09:33 PM by CCCC Link to comment Share on other sites More sharing options...

As said above I bunged a sensor in the fuel line that feeds the rail! So just before the rail is where I get my pressure reading from! I only really use it as insurance to ensure both 044's are working. But it does display high numbers Edited 08/01/13 09:52 PM by Kosij Link to comment Share on other sites More sharing options...
