Fuel-filler compartment drain

A heads-up...

The fuel-filler flap on cars is not (normally) designed to provide waterproofness and, when it rains or the car is washed, water will find its way into the compartment area behind the flap.

My 2009 Skoda Roomster's fuel-filler compartment has a drain-outlet directly below the filler-cap. The outlet's bore is quite large and any water collecting in the compartment rapidly drains away and disappears harmlessly behind the rear wheel-arch's plastic liner.

My 2024 Skoda Fabia Mk4's fuel-filler compartment also has a drain-outlet, but this is in an 'indent' to the left of the filler-cap and, more importantly, the bore of that drain-outlet's 'hole' is much smaller than the Roomster's. Consequently, if there is any dirt/debris in the water that enters the Fabia's fuel-filler compartment, there's every chance that the drain-outlet will clog up and a pool or water will then form. To avoid this happening, it's worth occasionally cleaning a Fabia Mk 4's fuel-filler compartment drain.

I use a length of thin plastic-covered electrical wire as shown in the image below (and obviously remove the wire from the drain afterwards!)
