On a tangent and apologies as it's of no help to the OP, but I recently saw this peculiar creation (LPG-converted 2015 Vauxhall Viva with the whole boot used for the tank - see picture 14)

Why on earth would you bother

Doesn't filling up and max delivery 100L at the pumps become an issue?

That's aside from obvious safety concerns (which can be addressed), lower mpg and poorer handling due to extra weight..

Not a big deal at the pumps. Stick in 100 litres, pop the nozzle back into the pump and wave at the person on the desk for a reset and then go again. I used to have to do it with my ChevyVan until 12mpg finally got to me...
