"I recently installed a rebuil
"I recently installed a rebuilt Yanmar 3GM30 from a reputable dealer who also lined it up for me. We went on a 3 week trip and while we were gone the engine ran well but has a few fuel leaks. Two "banjo" fittings leaked quit a bit and I replaced the copper washers on either side of the fitting. They still leak a bit but not nearly as bad as before I replaced them. I'm not sure how much torque is required and I'm nervous about breaking something. My main concern is that where the fuel leaves the injector pump there's three standoff kind of fittings and the fuel is leaking quit bad from the bottom of two of them. I talked to the rebuilder and he tells me that there are "O" rings on the bottoms of these fittings. If I remove the lines to the injectors I should be able to put a "deep" socket on them and tighten them, but I was wondering if I could use a "crow's foot". And by loosening the lines to the injectors try to tighten these units. First question again is what torgue should I use and what size are they? I imagine they are metric and I will have to buy some "crow's feet" to do the job. And one more thing ... should I replace the "O" rings? Sorry about the long winded question but I replaced the old engine because I'm and old submariner and my wife and I both aren't fussy about the smell of diesel and I hope to remove all leaks. Any suggestion to fix this would be of great import to me. Regards and thanks in advance."
