Fuel venting isn`t the problem, really? Air is 900 times less dense than fuel, right?..
I find it strange to have the vent as large as the fuel-line or bigger, could make it easily yes, but not a need to...
If you ever find a tank imploded, it won`t ever be the first tank..then! we`re into fuel lines..
All lines serving fuel must me scaled to the need, and if you add a wire from the ECU battery from negative to every separate fuel-line, you also eliminate static build-up. Just that easy. The battery absorbs it all, and eliminates it.
No special additives needed any longer..
I have four tanks in my kit, just pressured them slightly to find a leak, two thumbs up here. And since I got mine in glass, I`ll
wrap them in kevlar.
10 litres in those four sounds beyond..but if you say so
. Sounds like smoke..
