I’ve been using NAPA fuel filters for over 20 years in the shop. Their fuel filters are as good as the OEM filters, at about 25% of the cost. One of the concerns about the NAPA filter is that it doesn’t have the same overall outside diameter, creating fitment problems in some Ducks. I simply angle the securing bracket around the center band of the filter.
The gallery picture shows a NAPA filter and an OEM filter. Notice the center ring of the NAPA filter. It is the same diameter as the outside of the OEM filter.
NOTE1: Secure the NAPA filter in the fuel pump assembly of Superbikes and ST models assembly by angling the clamp around the center ring of the NAPA filter.
NOTE2: The MTS1200 takes a smaller fuel filter. The napa fuel filter is incompatible with the MTS1200
