In some parts of the world, the quality of fuel can be poor because the storage methods can lead to ingress of material such as dirt and sand. In Ethiopia, I was offered a few litres of free fuel, but politely declined and later observed leaves and debris from trees in the fuel—phew! I purchased the Twin Air fuel filter at the start of my round the world journey but didn't keep it for long.

The Twin Air fuel tank filter is a sock that sits underneath the fuel tank gap, which holds it in place. The stock fuel tank for the Honda CRF250L has metal bars inside the fuel tank preventing a fuel nozzle from going too far inside; thus, the fuel sock will not fit. I fitted the fuel sock on my Acerbis fuel tank (read my Acerbis fuel tank review here).

The Twin Air fuel filter works well at preventing ingress of debris such as grains of sand, which I observed in mine. It filters particles as small as 40 microns. It does not filter water or fine dirt that is common in dirty fuel.

Using the Twin Air fuel filter, I experienced dirty fuel and had to clean the inside of my fuel tank, my fuel filter, and fuel pump on my Honda CRF250L.


For me, the Twin Air fuel tank filter seems more suitable when the fuel is known to be of good quality but there's a risk of ingress from other sources. This could be refueling at the race track, windy conditions blowing sand in whilst refueling, and so on. To prevent ingress of smaller particles—for example, in black market fuel—a finer filter is required.
