Come on guys....think! Anyone who says I have to remove the engine will be put on ignore...

I have a pal with a major fuel tank issue, he has gained access to them by cutting a large hole in the hull. He is in the boat repair business though, his reasoning being fixing the hull is cheaper and faster than trashing the internals and the floor.

I don’t know about that.... I mean, what would you prefer after some repairs, a dodgy interior or a dodgy hull?

I think if you end up getting it done "professionally" they will go in through your galley floor and apart from the new flooring when it's done you won't know they have been there, your wallet might though.

Nice Pete .Good install of a tank given the space / boat L .
My old Porto 35 the S/Skr rival would have been an engines out job .Same for the geny .It’s AL tank looked a heavy duty piece of kit though with like cm thick welds .

I have never really countenanced a busted tank , Having read around the subject it boils down to a few factors .
Bonding AL - to prevent it fizzing away if another metal comes in contact .
Mounting AL , to insulate it from vibrations + flexing .
Quality of the thing . Up to the builder to pitch that , same with other components .

Get any one of the above wrong ……….

BOUBA might be a silly question but is there room for a tank some where else or even two one either side .

Ok. That’s original thinking ?
It hasn’t occurred to me. I suppose that the constraining factor is engine access and distance from filler cap.
But, yes, on the starboard side there is plenty of room, next to the black water tank. In fact, the fresh water tank is in that position on the port side.
It would change the balance of the boat but that may not be a bad thing....
Well done Seastoke! That has given me loads to think about
 
If I put the tank on the starboard side, it would stop me servicing many wires (everything runs down the crawl space. And I wouldn’t be able to service the macerator on the black water tank.
Also the tank would be long, and run fore to aft, so there’s a risk of starving the engine of fuel as the boat rocks up and down...
But the crawl space is big and is wasted space....

Are you realy debating with yourself on an open forum.
 
Instead of accessing the wires and macerator by crawling down the crawl space, I could put a lot of hatches in the engine room starboard bulkhead and service everything from the engine room.....
 
ok out of the box convert the water tank to to diesel then cut the end out of the old diesel tank put a liner in and use as water .

The water tank is only 300 liters and the fuel tank is 800...but it’s a clever idea...
 
Got it , do what google has done , drain the fuel put it in his car , put the boat on a trailer to save on mooring and just polish it .

Unfortunately I recently got a Tesla......
I could have run the Volvo car for months on what I’m throwing away....
 
250 replies and you have yet to find the cause of the leak, Having replaced the fuel tanks on my last boat a sea line F43 that were oversized from original build, I removed the furniture and flooring, to gain access to both tanks that were each side of engines, had new ones made identical to old ones so easy refit, added drain points to both ends, bilges cleaned up no problem , all done over a few weekends, if I was doing it again, I would , prepurchase the new tanks, remove engines and tanks, fit new tanks and drop engines back in again in one go, you could probably do yours with only moving engine back or just holding up, to gain access to tank.
If you find that it is your Feul tank leaking, and accept it has to come out, it's not that bad, worst part is finding it leaking,
Ours was damaged we think by being caught out in some very big sea,s ,that caused the Feul to break the weld on a baffle at the top off the tank, new tanks were made with more baffling,

Unfortunately a few events have happened at the same time, hurtling my back being a biggie. I’m much better but just unscrewing and rescrewing the sender was my limit today.
I feel that your advice is sage
