I am in the stage to get a fuel tank. I cannot weld ally myself, and I am looking for a locost solution for my fuel tank.
Anyone has some tips for alternative solutions?
Should I build one from 16 gauge steel?
I know a Triumph Spitfire tank should fit, but they are quite rare on this side of the Channel.
Anybody used a outboard engine fuel tank?? They are sqare and should be easy to fit...
Don;t think they are allowed
What about a steel version? I cant think of any reason why a steel tank could not be allowed? All the older cars have them...
you will need a bigger tank than both as those, i would say get as big a tank as possible! if you had that tank you would probably only make it to the
filling station and back again 
^ mines ain't much bigger than those
mine is 9 gallon and the petrol seems to disappear very quickly indeed
I am looking for a locost and fast to build alternative. I have a deadline for finishing my car, so I want to save as much time as possible.
I know the shown tanks are not ideal with regard to capacity and lack of baffles.
What about building a steel tank? I suppose it's not that difficult?
9 gallons? is that about 45 litres? mine is only 35 lol
if you can weld, without pin holes, then you can make a steel tank easy enough.
one piece of steel folded to make 4 sides, you only need to weld one seam. then weld on the two end plates.
What about rust inside? Could that be a problem?
a lot of production car tanks (maybe older cars) are pressed steel, the petrol should keep it protected inside.
The petrol and petrol vapour protects the steel from rusting 
Even if your welding sucks you can get gloopy fuel tanks sealants from Frost that will seal pin holes. Quite expensive though so might be worth just
buying one....
Like the lateral thinking though!!!
If you think you'll want to go what 100 miles between fill ups. Average 25mpg.
That means you'll need a 18L tank....
