Mine is 51 years old and doing fine. I honestly think Leo should name the manufacturer because he has always gone high end on all his choices so I’m wondering if it is Tek-tanks.
Stainless steel diesel fuel tanks?

Highly unlikely and not a great thing to suggest unless you have some very real evidence. Probably best to scrub the post

I don think they look anything like Tek-tanks. If you read the Tech-tank bespoke tank guide they don't use sealant and they use an interlocking baffle plate system that interlocks with the top panel to stop it lifting when under pressure. The tanks on Tallyho bulged under 3psi and had excessive sealant used. The Tech-tank features dont look similar to the tank in the video.

I thought the seams that Leo showed were appalling. I think he was very kind to them. Tiller Girl has stainless water and diesel tanks and survived without any trouble for 30 years in my ownership and more before that. I had a holding tank from Tek Tanks which I thought was absolutely excellent. I would certainly consider both options should I need a new tank.

There is obviously a bit of corrosion taking place, but I’m inclined to think « not a lot, and there are other bits of boat to worry over first ».
Should I start worrying?
The builders get top marks for the access hatches.

No. No worries at all.
And as another has said, Leo certainly wasn't using TekTanks.
I'd call this staining not corrosion

The Tek Tank is nothing like Leo's. Pressure testing certified on the label.

See posts #15 and #17.
Perhaps soldering with good size overlapping seams might be a better way of joining S/S for fuel tanks. There would be little corrosion caused by excess heat and added impurities.
Soft soldered tinplate tanks and containers have been used in thousands-perhaps millions- of applications since the steam age. Early 'Garden Gate' Manx Nortons had scalloped edges to the fuel and oil tanks to give a larger join area.
It is not new technology, but I expect the skills to do it are no longer in the workplace.
Soldering large items with a gas torch, bakers fluid or borax flux and a stick of Tinmans Solder is a black art, not a science.

I've heard of Hard Soldering a tank .... but never soft ??

You have no idea what you are talking about. I’ve not slandered anyone. You probably need some English lessons.

I've had 2 boat with SS fuel tanks.
Both leaked at the corner seam weld, in the must inaccessible place in the boat.
However, SS is more than adequate for a fuel tank, it's the inability of the manufacturer's to weld to a good weld procedure. This isn't rocket science, it down to designing the weld, prep', profile pre-heat (if required), filler rod, using the correct welding process and training the operator. If you use a well designed weld procedure it shouldn't leak.
My current boat has a rotational mounded tank, now 15 years old. No problems so far, except re-sealing the inspection hatch, which proved to be quite difficult.

I suppose it must be a headroom problem in TallyHo,notptting fuel tanks in bilge as in photos shown seem the best idea for weight and access

Given that you guys seem to want to blather on about this ....
BT - your post earlier 'implies' Tek Tanks ..... anyone of less knowledge of them - may be adversely affected by your naming .... whether intended or not.

Definitely a case can be made for a day tank tillable via a pump from other tanks or directly from a deck filler.

I think so, too. “Tally Ho!” is a big boat, but I recall that she carried and no doubt will carry a lot of inside ballast.
