I'm about to fit a new diesel tank to my MAB. The old one is a steel cylindrical model which at least has the virtue that the shape makes for something of a sump at the bottom where the gunge can collect. Funds are limited so I will be looking for something "good value".

In UK, the most common seem to be the Aquafix CAN models, and Mailspeed Marine sell these at a reasonably decent price. However, the high profile ones look virtually flat bottomed which seems to me to mean rather a lot of fuel effectively unusable. I also note that they are described as being made of polythene, whereas Calder says the best material for fuel tanks is polyethelene, which is what most other plastic tanks say they are made of. I don't know if they are the same thing, but I'd guess not.

A company called Pacer Marine sell a range of tanks branded Diablo. A quick google search says they are the discount brand of Nuova Rade. They are actually slightly more expensive than the CAN tanks, but they have more connectors than the CAN and a filler elbow included so they probably work out to be better value. My only concern looking at the picture is that the inspection hatch with all the connectors in it is held on by only 2 bolts, whereas there are usually more than that, and I wonder how effective the seal would be.

After that, the Nuovo Ercole or Plastimo tanks are a lot more expensive.

Does anyone have any experience of any of these or other makes, and any recommendations, good or bad? As said, funds are tight, but obviously this is something I only want to have to do once, so if there really is some major benefit to the more expensive tanks, I suppose I would have to consider them.

I believe polythene and polyethylene are the same thing.
Btw, I have a Vetus plastic tank and I like it. It is flat bottomed but then you don't want to get to the bottom of the tank anyway, so you?

They are cheap, basic tanks, but seem to conform to the necessary standards. The low cost (compared with custom made tanks) is because they are rotational moulded compared with welded. They do not seem to have baffles, although in the small sizes this is probably not a problem The fittings are also very basic. You might also look at Vetus tanks, which are more expensive but seem to have much better fittings. The big downside of these standard tanks is that they can be difficult to fit into a small boat, or rather the size that will fit gives a smaller capacity than can be obtained with a custom made tank. However, if you can work with this constraint then they are significantly cheaper. BTW the dip tube does not go right to the bottom, further limiting the usable capacity, but this is common with most tanks that do not have a bottom takeoff.

I have used them for separate heating fuel tanks on large boats, perfectly acceptable and no seams to speak of, BTW I could almost certainly do one cheaper than Mailspeed, not much, but if price is paramount it may help.

If funds are tight google 'Osculati tanks' , when looking to replace my Centaurs fuel tank the costs were in the region of £400 + fittings etc so getting on for £500. i looked at polythene and got the tank plus fittings for just over £100 from shop4tanks.co.uk, lost 1 litre in capacity but a small price to pay.

I fitted the Plastimo plastic tank - 91 Litres, it replaced a steel tank of well over twice the capacity but in practice it's not a problem, I have 24hrs motoring. The Plastimo mechanical gauge is pretty useless though, it became unreadable after a couple of years and replaced with another 'proper' mechanical gauge.
