Over the years I have always encouraged other flyers to filter both the glow and petrol fuels. The lines usually get blocked through negligence or poor maintenance and the fuel can allows dust in over time , especially when its windy and the lid to your fuel is off!
It is worth investing in a fuel line filter which fits between your fuel can and the fuel line to the engine. There are many different types, I have had great results with the Axial Anodised Filter. You know it makes sense to go to the flying field to fly and not have to mess with your model due to contamination in your fuel system…….So treat yourself to a filter and while your at it some Byron fuel!!!
