## Before you buy

- Fitment and the claimed oil-separation function are listing claims, not independently verified. Confirm the exact vehicle year, model, engine and existing part number before purchase.

## A good fit for

- Owners sourcing a replacement separator for a listed 2017–2019 Ford Super Duty 6.7L diesel vehicle.
- Buyers whose existing part number matches FC3Z-6A785-F or FC3Z6A785F.

## Less suited to

- Vehicles outside the listed models, years or engine unless fitment is separately confirmed.
- Buyers who need independently verified compatibility or performance evidence.

## Customer feedback

Only aggregate ratings are supplied, with a very small number of ratings and no written feedback. That provides little basis for judging fitment, installation or durability. Buyers should rely on confirming the listed vehicle and part-number match rather than treating the rating as proof of compatibility.
