[C320-list] Yanmar 3GM issues

 Lou,Before you go crazy, check the Racor filter.  It's pretty easy to get that clogged up if there is crud in the tank, or a buildup of water.  I'd start right there.  If the Racor is clogged, also check the fuel filter on the engine.  Depending on what you find, if there is stuff in the filters, you might want to look into having the tank cleaned and the fuel polished.One other thought, how old are your fuel lines?  I've seen this on old cars.  If the hoses are old, the inner lining can separate and cause a blockage in the line.  Fuel won't flow, or you just get a trickle.  Just something to keep in mind.

 Hi all, looking for thoughts here- went out for a sail today -engine took a lot of priming to start but then was fine. After 2 hrs sailing it wouldn’t turnover despite more priming. Had to sail it into the mooring.  Someone suggested  maybe a fuel line clog or I need to change the primary fuel filter? Both fuel filters were changed upon launching in May- would it make sense to change again ?  Picked up Nigel Calders book on diesels but still learning.
