The only material able to last with all these "new mix of agessive fuels" is VITON it can be bought as o'rings but also flat sheets ; pricy but very effective when the seal is constantly in the the liquid.
Another solution is when mounting a cork seal to use extensivly that red mixture ( liquid ) plane homebuilders use to cover inside their wood wing tanks ( once cured it's like rubber ; only issue this product is very very pricy and rare to find in small quantity !! ( I used to borrow some at the aeroclub workshop not far fom my place !!

PR1005L probably Michel. Red and really smelly? It works really well for normal jet fuel and avgas (usually leaded) but I've heard that unleaded petrol with aromatics (toluene etc) will disolve it, but I don't know for sure, one guy tried it in his motorbike tank. I spent far too much time inside the wings of aeroplanes painting that stuff around when I fiest started, fairly standard job for the apprentice!
