While prefiltering during refueling, you can easily clean fuel pump filters instead of continously changing them to keep the motor running smoothly.

To mount it, simply remove the “shield” shaped flange, insert the media helping the corners with the head of the cable tie (in the package), align the filter with the bike axis, push the cap level with the tank surface and simply mount back the “shield”, done.

For the CJ Design billet small cap Acerbis adapter, the filter can be either mounted on top below the screw cap or under the adapter.

The new filter combines the extra fast HDM3D filtering media with the installing-friendly drop-in adapter, filter has a huge filtering surface of almost 1200 square cm combining a very fast refueling with optimal EFI fuel pump and fuel filter protection and the latest and unique welded edges tehcnology.

This will protect the fuel pump, the original strainer works between 60 and 100 microns, and prolong the fuel filter life (KL15 or KL97 depending on year of production)

In both cases the filter is really small and can clog very fast, plus the fuel pump is exposed to all kind of particles and water contamination, the neck prefilter will prevent all this saving the EFI system and preserving it for many tens of thousand of KM.

Double-check your bike’s make, model, year, gas tank design, filler nozzle, etc. before ordering. 
Take careful measurements of your filler nozzle and confirm for proper fitment. (see measurements of filter above).
If you order the wrong filter you’re responsible for any shipping fees needed to replace it with the proper filter, plus any price differences.
Filters that have been immersed in gas (or are not in like-new condition) are NOT eligible for return or refund.
