Fits BMW F650GS Dakar / G650GS Sertao (same type system)  that have the metal filler nozzle as shown below.
(formerly part number M26006)

Filter does not have a flange on top – instead the black ring fits in the tapered filler nozzle of your gas tank.
Neck size 35mm.
Filter bag size 4.5×7.5″
Filter bag is offset from the nozzle.

If you have a red filler nozzle you can modify this filter per the video below.  Guglatech is working on a red filler nozzle kit, stay tuned.


Special fuel neck prefilter designed to be mounted inside the original fuel cap, simple drop-in easy to insert and extract, no further modifications or mountings.

Expedition media, XL+ 600 square cm of filtering surface, simply mounting and fast refueling, washable and long lasting.

The HDM3D Media will allow a very good protection of the fuel pump and main filter, Acquastop separating water from fuel during refueling.

The original system has a strainer working between 40 microns, plus the other more sensitive filter is a nylon mesh which is totally inadequate to protect the fuel pump.

This filtration level will both preserve the fuel pump and prolong the original fuel filter.

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.
