I took a video of some mods that you might be interested in. Particularly around the 2 minute mark I show some racor mods which will make bleeding and filter changes super easy.
https://youtu.be/H-GI38vE4hQ I touch on the bleeding process on my 3HM35F in the next video. I usually have very little need to bleed anywhere except for the racor but if I do, I avoid at all cost operating the bleed screws. I crack the banjo fittings instead. The bleed screws have a bad habit of leaking and getting stripped easily. The copper washers in the banjo fittings MAY weep if not replaced but at least it will stay put. On multiple occasions I have found myself scrambling to find bleed screws which had "blown out". https://youtu.be/mdHIt14l0R8 If you are considering polishing the fuel yourself I suggest getting a cheap 12v fuel pump. I found one on ebay for ~$10. You can install the pump on the inlet side of the racor and then remove the fuel return line from the injectors and attach it to the outlet of the racor. This creates a recirc flow path. At ~20 gph you would be well served to leave the pump running for at least 2 hours. 10 hours would give a lot of confidence for a delivery trip. I would also suggest rocking the boat as much as to can during the recirc. http://www.ebay.com/itm/252681327818 Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Jan 28, 2017 1:35 PM, "Bruce Whitmore via CnC-List" < [email protected]> wrote: > Hello all, > > > The engine in our 37/40+ is a Yanmar 3JH2E.
