Re: Stus-List yanmar 2gmf in 29-2
In my video I discuss how I bleed my engine. I show JB weld stick on the HP injector bleed screw which is notorious for leaking/coming loose. As Russ says, the bleed screws on the filter also regularly leak so I plug those with JB weld as. The banjo bolt going into the lift pump is (IMO) slightly too long. It tends to bottom out and not provide good enough tension on the gaskets (copper or dowty). I've had the most success by doubling up the dowty washers on that particular bolt.

Hi Bev, I had a leak at the bleed screw gasket on a filter top. Being the filter between lift pump & injector pump. I verified the location by putting little wraps of paper towel around the system connections. The leak quickly discolours the paper towel, even before you can smell it.

Fuel can leak from just about anywhere (:-). If you have a Racor filter, there are numerous places - mine was leaking from under the manual pump that is used for priming. Good luck.

Re: Stus-List yanmar 2gmf in 29-2
All your fuel lines are external so finding leaks should be a matter of running the motor and looking and feeling for moisture. Is fuel puddling under the motor? Copper sealing gaskets around banjo fittings should be replaced each time the bolt is loosened when you bleed the system. I keep a dozen on board for this reason. Feed lines to injectors also need to seat securely or fuel can leak. My 3HM had a leak from the filter housing right before the high pressure pump caused by over tightening the cap which cracked the thin aluminum casting. Any little thing can cause a leak.

Fuel leak into the engine? Or out? What signs and simptoms are you experiencing?
