Designed as a replacement for the corresponding original equipment filter in compatible Mercury / Mariner fuel systems.
OEM part numbers are used for identification and compatibility reference only.
Important – Check Compatibility
Not all Mercury or Mariner 75–100 HP engines use the same VST filter.

If the part looks the same as yours, it is not always the right one for your outboard.
