Fuel tank ...

Does anyone know where I could get a single tank to fit under my console. Console currently has a 70litre tank with dimensions 800mm long x 350mm wide x 300mm high. Humber sometimes fit 2 x such tanks in the console needing to switch between the two, which is fine, but I wonder if anyone has come across a stock plastic fuel tank that would be around 800mm long x 700mm wide and 300-350mm high? There may be scope for a tad more width but not much and custom plastic fuel tanks are a no go cost wise (ie cost of moulds would be £000ís

Otherwise it looks like a stainless or aluminium custom tank if I were to go down the single tank route.

Thanks!

Look for www.shop4tanks.co.uk. They do a range of plastic tanks and one similar to your size requirements. It’s around the 120l capacity

Thanks, the 102 litre tank would fit but the 120 litre tank is 950mm long so probably wonít fit unfortunately. Shame there doesnít seem to be a 800mm long x 700mm wide tank around!

Fuel tank ...

The alternative stainless / aluminium tank quote has come in at £430, this would be 800mm x 700mm x 300mm and provide 168 litres of capacity.

For £460 (aluminium 3mm) or £475 (stainless 2mm) the tank size could be 800mm long x 800mm wide one end and 700mm the other x 350mm high. This would provide 210 litres of capacity. Any thoughts?

Tek Tanks do a suitable for petrol range. A quick look suggests they don't do an 800x700x300 but they do an 800x350x300 so you'd be back to two tanks.

Tek Tanks don't seem to make custom tanks for petrol.

What about a stainless tank?

Yeah the 800x350x300 is essentially the one I have now at 70 litres. My post above provides quote received for metal tank, no experience of these though - but know they are widely used

Same company that provided the quote - hard decision aluminium versus stainless. Both marine versions of the material but apparently aluminium corrodes more, stainless apparently has far better corrosion properties but with less flex may be more susceptible to joint cracking along weld lines ... all what I have heard not experienced

Cracking along the welds was the fate of the original tank otherwise it looked perfect.

I've had 25yr old American sports boats...aluminium tanks and never had an issue but either is likely to last as long as you'll keep the boat. (The aluminium tank, even at 3mm, is lighter than 2mm stainless)

Look to the people that know ,i suspect the american boat industry has put many thousand times the amount of tanks into sports boats than we have , and if you think about it theres more duff tanks on this forum than you would expect ,i dont know why !,my us built rib has a huge 240 litre tank and its def ally ,maybe if you research a us sports boat manufactur who has a number of grades of finish, and see where it leads , what i mean is if brunswick corp have ally tanks in binliner and maxum but stainless in searay then you can assume stainless has the edge but if searay has ally tank you can probhably assume ally comes out best . just thinking out loud really ,may be helpful !

Aluminium is a third of the weight of stainless for the same thickness.

Aluminium is less forgiving of poor workmanship.

Aluminium is more prone to galvanic corrosion where two dis-similar metals e.g. stainless and aluminium are mixed although stainless will corrode in the wrong circumstances.

There are pro's and con's of each. Decent fabrication, good location and well supported I'd go aluminium, otherwise I'd go stainless. My Pac 22 tank which was stainless was 26 years old when I removed it and other than being a bit dirty was in perfect condition.
