The direct Cummins 3959612 \/ Fleetguard FF5488 cross-reference makes it easy to confirm for customers who have a Cummins service record or existing filter box in hand. At $45.38 it is strong value versus OEM Cummins or Fleetguard pricing.

Always clarify that it is a fuel filter only, and ask whether the customer’s fuel system has a separate primary water separator that also needs servicing. The second common issue is customers ordering by thread and dimension from a generic cross-reference without confirming the micron rating — the 4-micron absolute specification is important for ISC 8.3L injection system protection and should not be substituted with a lower-efficiency filter.\u003c\/p\u003e","brand":"FVW","offers":[{"title":"Default Title","offer_id":43563795316772,"sku":"BF7815","price":45.38,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_998400bd-eb94-49b1-b51d-21a893beefa6.jpg?v=1788808240","url":"https:\/\/marisolmarine.com\/products\/baldwin-bf7815-high-efficiency-fuel-spin-on-filter","provider":"Marisol Marine Company","version":"1.0","type":"link"}
