yes, fuel is just a different branded safer bottle, made by the same company and everything. I use a fuel bottle and it is honestly the lightest tank I've used, even lighter than my old guerrilla 0.8l tank, would seriously recommend it.
Ive heard a lot of people saying they've had air blisters on these bottles my mate had to send his back dueto a large swelling apering round the top od the bottle BZ swapped it straight away but they dont sound too safe
Never had any issue's with mine while i had it,but i have heard about a few having blister issue's which is worrying,but if anything i found the 1.2ltr bottle too short for me personally after using a generic type Pure Energy bottle.
i wanted the 1.5 but hearing about the bubbling put me off tbh, I know bz changed my mates one but does make you think what could of happened 4500psi is a hell of a lot of pressure
