Please excuse me. I didn't realize there was an archive. I'm looking
through it now, but it's slow going for lack of a search function. But
I am looking. Just so I'm sure we're talking about the same hoses, do
you mean the 4 hoses that go from what looks like the thermostat
housing to the manifolds? When you said rear of the manifolds, I got
confused. You mean the end of the manifolds closest to the front or
rear of the boat? The only ones I'm seeing are the 4 towards the end
of the manifold facing the bow of the boat.
Does that make sense?
