Petrol Tank, plastic/Aluminium
Whats the main advantages/disadvantages of a plastic tank rather than a aluminium tank?
For I guess it's a lot lighter - any downsidws other than cost?

There's quite a history of plastic tanks springing leaks - do a search on here.
I had one - it leaked

With the need to use thicker plastic sheet than ally sheet is there any significant difference in weight, particularly as a % of the weight of the
tank + petrol?

Custom make a GRP tank. That way you can make it exactly the size you want. You would need to use a fuel reistant resin/gel but then, the world is
your oyster!

plastic tanks can work. We use 1800L water tanks at work. When we first started using them they burst quite a lot. Now, a few years down the line,
they only burst when we accidentally put a 10bar pressure fed supply into them.

we make plastic water and chemical tanks at work, i'm the design engineer, they just need to be designed to take whatever your putting in to
them

In all fairness, it was one manufacturer off this site who allegedly was given sub-standard solvent. Unfortunately that chap unsubscribed after a
large number of tanks started to leak. It has to be said that many of the ones he made didn't leak - but there was always an element of doubt
after that.
Plastic tanks have been used in the motor-boat world for decades with no problems - it depends on the standard of construction and the quality of
materials.
In my case, I bought an aluminium tank from a reputable supplier (Allyfab) purely for safety's sake. Cost not a lot more, but I was more than
happy with the product.

Tek tanks can make plastic tanks any size you want, they also do a range of standard ones which I'd expect are much cheaper.
http://www.tek-tanks.com/
Another source is Rally Design who sell American Jaz tanks.

Finally do a search on "deneo" he's been known to make aluminium tanks for board members.
