Fire is always a worry with VWs, and especially with plastic ones. Check your stuff often, particularly where the fuel line comes through the tin (there’s supposed to be a grommet there, but there’s probably not, so use a bit of neoprene fule line).
I moved my fuel filter out of the engine bay last year, but might put it back next year. I never see it where it is so if it comes loose there’ll be a lot of spillage, at least.
Good to have an extinguisher in the car too.
