Hi Will,
Wonderful work. Congrats.
I=C2=B4m building a rather modified XS MG (conventional LG, center truss ou
t of
4130 cage anchored in the reinforced sidewalls). Having removed the plastic
tank and making one out of aluminum with larger capacity (live in a big
country - Brazil) I weighted the plastic one. A whooping 6+kg (can=C2=B4t
remember exactly how much past 6). The alu one will weight about 4kg and
will hold almost 8 gallons more.
Consider using a fuel sealant inside, even a 3 layer is expected to have a
bunch of pin holes and make the tank leaky.
Best
Wlad
