Les Henson Posted May 6, 2009 Share Posted May 6, 2009 Only fuel lines and the regulator there. Was the gasket changed at the same time? There's two types if I remember right, and you must replace it. The regulator leaks from the diaphragm housing, and you can see very clearly if you look from underneath the engine. Diaphragm will drip, gasket will leak down the side of the block. Les. Quote Link to comment Share on other sites More sharing options...
