Thanks for your reply! I got a nippon water seperator. This is ideally mounted before the feed pump. Does it have a filter and glass bowl? How much did it cost?

Sa oil leak question ko, i just meant if there was anything out of the ordinary that might be causing the oil leak. Ok, i will doublecheck the usual things like tightness, or even wether the flange surface is contacting the filter correctly(??), etc.. Check the square-cut oring which goes into the groove of the filter head. Thanks again! patrick
