It is unlikely that fuel line down stream of the lift/priming pump is leaking to the extent that air is getting in since this section is under pressure. I would look upstream of the lift pump. This section is under vacuum. The upstream fuel filter (not the one mounted on the engine - often made by and referred to as "the racor") is very likely to be the problem. The rest of the fittings and connections rarely get disturbed but the racor does. Some racors are difficult to fully bleed and ALL of the interfaces which are disturbed during filter changes should be suspect.
Rule that out and then we can talk more. In the mean time check out these videos for fuel bleeding and racor mods. https://youtu.be/F7KD1_EZmU4 https://youtu.be/H-GI38vE4hQ Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Sun, Oct 4, 2020, 17:24 General Gao <general.z....@gmail.com> wrote: > Hi everyone, > > Again, looking for advice from experienced sailors. > > Today on my trip, my Diesel engine stopped frequently.
