The most common situation we see is customers sourcing only the pressure sensor or only the pressure limiting valve separately, then discovering the seals are also needed once the rail is already open. Ordering this kit upfront covers all three critical components in one purchase and avoids a second order mid-job. Because the same common rail architecture is shared across Volvo Penta marine, industrial, and heavy equipment engines, this part number has broader application than most — but serial-number confirmation is still essential before ordering.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563983831076,"sku":"20973777","price":888.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/431abf30-b693-476f-8c2d-4a3bdc473f14.png?v=1787336230","url":"https:\/\/marisolmarine.com\/products\/volvo-93","provider":"Marisol Marine Company","version":"1.0","type":"link"}
