Acerbis tanks With the MDR system bolted on to the tank.
This new 2019-2021 ACE0002 Mk5 filter is designed to live inside the Acerbis MDR mount, and does not interfere with the fuel cap or seal and now has some added cross ventilation and made a bit more solid as well.
Unlike our Original MK3 filter, there is no modification is required to the MDR Mount at all.
The new MK5 filter has extra venting in the plastic mount and has a great filtering speed.
Please note that the “MDR” system is the black section bolted on top of some new Acebis fuel tanks.
If it where the threaded section is made out of different plastic from the tank.
If you Acerbis tank has the threaded part of the tank, that is all made out of the same plastic from the tank, then you need the ACE0001 MK4 filter.
