Something is wrong if you are getting issues with your breathers, when filling up from a syphon hose, suggest you try it at home first before any changes, generally I found reducing the fuel flow volume solved it for me.

I have a 2009 model Yalta 555 HC and it has a 150L tank in it.
It is also a mongrel to fill for all the reasons you guys have explained. The petrol station I fuel up at slopes down hill so the fuel filler hose is at the high side of the driveway. I fill it with fuel until the fuel is visible halfway up the filler hose therefor being higher than the floor and the rest of the tank,this is after all the whistling and fuel splashing out the breathers and filler hose. Seems like a poor design and waste of fuel so I'd be interested if your plan works.
Bait is better.
Is that 2 breather vents on the back of the boat or did they join 2 into 1?The yalta has a air breather at the back and front of the tank which went into the splash well. The filler is in the rear of the tank at the stern. So on an angle, it won't push to the front and just comes out the rear breather and the filler pipe. Defective by design!
If it's 2 could one be blocked up with salt, happened to me quite a few times & enough to flatten the primer bulb & starve for fuel.
There seems to be something not quite right about this, I'd try & figure out what's really going on rather than make drastic changes.
Mine is an 03 hull with the larger tank, apparently. Never had that problem. Always fill slowly when I know its getting to the top. Mine usually clicks off at about the same time as the breathers start to spurt fuel. I can hear them breathing before this happens though. Have you ever drained it completely and tried to fill to see how much you can actually get in it?
2 into 2 mate. I assume it's not blocked as fuel does went out of them. The best I can figure out it's all about the angle. I'm not the sharpest tool in the world, but when your filling a tank from the rear when the front is facing upwards, it's near immposible to fill the whole tank as it'll just want to come out the filler which is what I'm seeing. Right?
Good to talk all this out before I do a drastic change, but best I figure, filling from the front will 100% solve my issue.
I have not drained it to see yet. I'ts an 06' model, and this was the year they changed to 150ltrs, but in the ass end of 2006, so I just gotta get the date of build on my hull. I don't have the sticker on the tank like the other guy has, so fingers crossed it's actually 180.
How about at sea, have you tried to fully fill her then? I don't like this guess work buisness when you're 100ks offshore for 3+ days.
The tank on this boat is an absolute nightmare to try and get fuel into while at sea.
Being extended overnight trips there is a lot of extra gear on the boat with large eskies and ice,fish fuel drums and people and the boat sits lower than normal in the stern.
Add 2 people at the rear trying to fuel the boat makes it sit even lower in the rear which is compounding the issue.
The filler pipe goes into the rear end of the tank which is a lot lower than the front of the tank and it seems to get a huge air pocket up the front end
It gets to the point where the filler pipe is full but there is no way of guaranteeing the tank is actually full which is not safe on the long trips to the outer reefs.
There is already an inspection port in the floor over the top end of the tank so we are thinking of fitting a larger port or small hatch cover and fitting another filler in the high end of the tank which will solve all issues.
Being a plastic tank we can drill a pilot hole with a hand drill and cut the filler hole with a hacksaw blade quite easily without any danger.
My concern there is two fold. Firstly there is virtually no room at the inspection port at the front so how do you pipe into it without the hose sticking up out of the deck and becoming a trip hazard and pain in the a$$.
Secondly if you drill a hole in the tank how are you going to fit the filler hose and ensure that you aren't going to get leaks and compromise the integrity of the tank. The filler attachment on plastic tanks are a moulded extrusion(pipe) that sticks out. You will have to find a fitting to screw into a thin layer of plastic and hope it doesn't get loose or crack around that point. This would still be a concern if you were able to go into the side of the tank.
Not saying it can't be done but those would be my concerns.

Ozy there will be no filler pipe fitted.
If we decide to go this option we will use a flush mounted filler cap onto the flat section of the fuel tank, just to the left of the breather outlet.
It will have a gasket and be sealed with something like sika and screwed just like the fuel senders are fitted.
I cannot see any other options with the stupid setup that Yalta have done here.
Realistically these fuel cells should have been fitted the other way around so that the filler pipe is at the bow end and the gunnel mounted filler cap around midships and not all at the stern and at the very lowest point.
Is there enough room at that point for the actual hose to fit? Not sure how much room there is at the top of the tank . Filler hose is usually 35mm or 50mm. I would just go and look at mine but having sold it I am trying to go on memory as to how much space there is and if the hose would fit without bending and kinking it.

Don't think there is. You're looking at most 3cms. With an access hatch, it'll be easy to reach with the fillter attached direct to the tank. Bonus points for actually being able to see into the tank.
Ah so no hose running to the side of the boat. Just fill straight into the tank then?
Remember to always log on before heading offshore.
Yes fill straight into the tank.
The tank filler will be fitted directly into the top of the tank at the very highest point.
As Julian said there is roughly 30mm between the underfloor and top of the tank.
Once we fit an inspection port we also pickup the 15-20mm floor thickness so we will have roughly 45mm minimum under the port.
The fuel filler fittings are roughly 15mm high so there is ample room if we decide to go this option.
I noticed yesterday that no floor fittings have been sealed on the cutouts so while we are at it we will remove all the floor plates and seal the timber flooring properly to keep any rot out.
Check all the seat box screws, the fittings for the rear seat boxes and where the ladder attaches to the boarding platform.

I think Julian is going to remove the seat boxes and fit seat frames into the boat so the large eskies can sit under the seats to open up the rear deck for more fishing room.
Once he does that we can fill and seal all the seat base holes.
You would think when they make the cutouts in the floor that they would seal them, even if it was just with some paint.
