I'd always relied on the OBs own fuel filter under the cowl until I suffered what was put down to a fuel contamination issue with my Suzuki 20 on holiday this year. I immediately added a generic plastic inline filter from the local chandlery as in image below.
During the high temps this summer it has gone quite pliable... the part where the barbs join bending with the tension from the way the fuel lines curve away from it. I also worry if stood on by accident it could just split apart.
I was wondering if anyone has used the glass type with replaceable element like this from Moeller in the link below which looks neat and a bit more durable...

Whatever I get it must be a see through type so I can see the fuel and filter condition.
