I have a feeling I know the answer to this before I've asked it, but is it possible to make an aluminium fuel tank without welding? I'm
thinking of folds to form most of the edges, but then some sort of physical and chemical join for the other seams. Basically rivets and a petrol
resistant adhesive?
My initial plan was to weld up a steel tank, or even to follow the locost method and find a suitable tank from a donor. But if I can make it in
aluminium I can save the headache of corrosion.
Or are there other ways of holding fuel? Has anyone tried a plastic tank?
It is possible to fabricate a riveted alloy fuel tank.
After all, they have been used in the aviation industry for years.
You would need to research the correct sealers & rivets to use.
I am sure you'll find some good articles on the tinter web.
Not sure how you will stand on IVA testing though.
I'm pretty sure I read a long time ago that plastic tanks were not allowed due to the risk of them splitting.

Ah. I stand corrected.
you may not like this but to save a lot of hassle buy a tank

Why don’t you want a aluminium tank welded? surely it would be easier to make than
the sealant and rivets version? what would you do about outlet? and filler neck? as i
can’t see how you would river and seal them?

When you say that you can weld steel, you mean mild steel, and using a MIG?
So how different is that to MIG welding stainless steel, corrosion solved.
i’m not far from you and i have a tig welder your welcome to come and use to make your tank?
i you want to save some money.
What is wrong with a steel tank? Millions of cars have them. It will last as long as a steel chassis.
It strikes me that you have three choices.
1. Make a steel one.
2. Pay someone to make a stainless or ally one.
3. Buy a TIG. Learn to use it. Make your own tank. (By far the most costly solution)

p.s.
Number 3 gives the most satisfaction.
Option 4. use my tig for free and make one (cheapest option)
But i would take option 3 because you can make anything else you need to
make once you have brought a tig welder

Worth £168 all day long... Could have bought it and installed it by the time you've weighed up all your options.
I do also agree that buying a 'TIG' and making items yourself would be the most satisfying, however if 'locost' is your thing a
decent TIG can be expensive, although saying that, you can get cheaper 'lidl special' types...
i do agree with you, easier to buy one if you don’t have the option to buy a tig welder,
but like i said he can use mine for free and just buy the material or buy one done!?
For alloy tank joint sealing use PPG PR1422 A1/2 or A2 sealants. This is the stickiest sticky stuff you will ever find. It comes in various
viscosities but the brushable one is called PR142 A1/2 or PR1422 A2. The numbers refer to the working time - 1/2 hour or 2 hours. It will seal
anything to anything and is the most vile thing in creation. It is used to seal aircraft integral fuel tanks.
It will get everywhere and you will never get it out of clothing. It is also resistant to pretty much everything so once it is on it stays on and is
also a pig to remove once it has cured.
Apply wet to your joints and assemble. Brush the joints inside and out and clean up quick.
Can also vouch for "PRC" as its known in aircraft industry ^. It will literally stick anything to anything and seal against fuel no problem.
