Giles and Paula's Great Retirement Adventure
-
There is a breather pipe, so there should be no need to crack the filler cap. Our current assumption is that it is blocked. It works fine until the tanks are at about 30-35% full, then the port tank gives up. It does not degrade, it falls off a fucking cliff......

@Giles Doesn’t sound like it’s anything between the tank, fuel line, water separator, fuel filter, and the fuel rail and your theory of venting sound’s right.
If it was the fuel pump or fuel rail, the problem would manifest itself much earlier than the 30/35 percent fill.
Have you tried running the tank with the fuel cap removed on the port tank? If the vent is causing the issue, then no filler cap on the port tank would ensure that it’s getting enough air (as long as it’s semi protected to keep seawater out).

...and a off the wall thought...I wonder if the pickup wasn't properly placed in the tank and is only 2/3 of the way where it should be. Maybe you're running out of fuel because of it's placement.
Edit: The more I think about this, the more I think that this might be your issue especially for the way you describe it falling off.

Not that I'm an expert on fuel tanks, but I did do similar work with water tanks with pumps. There should be 2 tanks with a line between the 2 that would equalize the 2 tanks. Sometimes something as simple as the filter on the one tank would become clogged or challenged and would mess up the one tank.

@ROman We have been running them separately. But we can, with a flick of a valve join them. One of the things I will do when we are home is install a fuel pump and diesel polisher on that pipe, so that I can shunt the fuel from one tank to the other cleaning it with each pass. We had that system on PILGRIM and I am pretty (read, fucking)( surprised we do not have it as standard on SAKURA....
-
Could the fuel feed and return line be round the wrong way. Based upon the drawing...if the feed line is coming from the top of the tank as the fuel gets below the pipe, thats when the airlock/vacum is created?
-
What I know for certain, is that it runs OK between 100% and 65%. Just going to make sure we don't go below that until Sasga engineers have been and looked....
-
The weather is bad and predicted to get worse through the day and night. It would be foolhardy to continue and put SAKURA through a lot of stress (we are slamming into big seas), so we are running back to Brest. The weather across the channel is forecast to be awful for a week or two. so we will get home without SAKURA, and come pick her up as soon as we can.

now that’s not a happy ending

They say there are two kinds of sailors, those who have hit another yacht, and those who lieWell, thank Christ, I longer have to lie.....
I misjudged the crosswind today and sideswiped this.
The British captain was awfully nice. When I went onboard to apologise and assess the damage. He seemed to be more concerned about me and the damage to SAKURA. I said that I was not sure what to do in this situation, he told me to relax, fuck off and not to worry....
Go large, or go home.....

This first journey keeps getting more epic. Sakura is giving you the full experience.
