I have found that the 3HM35F (almost the same engine) primes very easily. I make more than problems by opening the official bleed screws. They will perpetually leak. In fact, I JB welded the screw on the engine filter and the HP pump in place. I have replaced the associated banjo fitting copper washers with seal washers. Yanmar makes some which I can provide the part numbers for or you can use seal washers from McMaster-Carr. This was a huge upgrade that completely eliminated fuel and air leaks.
I have also installed a priming bulb in the fuel supply line which helps prime the entire system including the racor. When I prime the system I prime the racor and then I only loosen the fuel banjo fitting into the engine filter. Once it is clear I loosen the banjo at the HP pump. 2 points and that's it. With copper washers you need to replace them but with seal washers they are reusable. https://youtu.be/mdHIt14l0R8 https://youtu.be/H-GI38vE4hQ Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Fri, May 4, 2018, 6:06 PM Nauset Beach via CnC-List < cnc-list@cnc-list.com> wrote: > I pulled the fuel hose off the tank pickup nipple as part of cleaning the > tank – though did not really need to do so.
