The HDM3D media filters down to 10 Microns, which will allow a very good protection of the fuel pump and main filter. WATER, and other contaminants (liquid and solid) will be separated during refueling.
The original BMW fuel filter system has a strainer working between 40 and 60 microns, made from nylon mesh, which is totally inadequate to protect the fuel pump.
This filtration level will both preserve the fuel pump and prolong fuel original filter life, thereby avoiding nasty surprises and high repair costs.
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.
