2017 Rules

[Percy W]

The rules Part 3 6E do not allow more than one 10l fuel can in the pits at a time, defined as the area between the pit counter (inner wall) and the track. I see no restriction against having a second fuel can behind the wall and exchanging cans during one stop.

Agreed!

Regarding the fuel can, the 10L can is heavy enough when full. I've noticed fuel spill from a 10L can when trying to rush during a pit stop. I don't think i'd be comfortable using a can bigger than 10L. Maybe a quick fill can would be different, but i have no experience using one of those.
