Product info:<\/strong>
\nA new sensor has been developed for D3-D6 engines that fits, for example, fuel filter \/ water separator 877763, 877768 & 877764. The sensor is connected to the EVC system and provides the alarm on your EVC instrumentation. It also works in parallel with an existing engine-mounted ‘water in fuel’ alarm.
\nThe kit fits D3\/D4\/D6 engines produced in 2011 and later (with a connected engine wiring harness). For 12 V or 24 V systems.<\/p>\n

Water in fuel alarm
\nTo receive an early warning for water in the fuel tank, the best position for a water sensor is in the fuel filter \/ water separator between the tank and the engine. The sensor detects water in the bowl of the water separator and provides the desired early warning.<\/p>\n

Volvo Penta water-in-fuel alarm 21641493 is an original sensor and alarm kit for D3, D4 and D6 diesel engines from model year 2011 with a connected engine wiring harness. The sensor is installed in the fuel filter\/water separator between the tank and the engine and detects water in the fuel bowl. A warning is displayed on the Volvo Penta instrumentation via the EVC system, so water contamination is detected at an early stage. This helps prevent corrosion, injector damage, poor running or engine shutdown caused by water in the diesel fuel.<\/p>\n

Main features and benefits:<\/h4>\n

Water-in-fuel alarm:<\/strong> Detects water in the fuel filter\/water separator.
\nFor D3, D4 and D6:<\/strong> Suitable for Volvo Penta engines from 2011 with a connected engine wiring harness.
\nEVC integration:<\/strong> Provides an alarm message on the Volvo Penta EVC instrumentation.
\nSuitable for 12\/24V:<\/strong> Can be used in both 12 Volt and 24 Volt installations.
\nFor water separators:<\/strong> Fits, among others, Volvo Penta 877763, 877768 and 877764.
\nEarly warning:<\/strong> Helps prevent damage caused by water in diesel fuel.
\nParallel operation possible:<\/strong> Can work together with an existing water-in-fuel alarm on the engine.
\nOriginal Volvo Penta part:<\/strong> Ensures correct fit and reliable operation.<\/p>\n","protected":false},"featured_media":448525,"comment_status":"open","ping_status":"closed","template":"","meta":[],"location":[],"product_brand":[25896],"product_cat":[30599,2585,22115,2716],"product_tag":[],"class_list":{"0":"post-448523","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-volvo-penta","7":"product_cat-volvo-penta-fuel-supply","8":"product_cat-engine-parts","9":"product_cat-parts-by-brand","10":"product_cat-engine-parts-volvo-penta","11":"product_shipping_class-parcel-0-10-kg","13":"first","14":"outofstock","15":"sale","16":"taxable","17":"shipping-taxable","18":"purchasable","19":"product-type-simple"},"group_of_quantity":0,"min_quantity":0,"max_quantity":"","exclude_order_quantity_value_rules":"no","exclude_category_quantity_rules":"no","combine_variations":"no","locations":[],"_links":{"self":[{"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/product\/448523","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/comments?post=448523"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/media\/448525"}],"wp:attachment":[{"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/media?parent=448523"}],"wp:term":[{"taxonomy":"location","embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/location?post=448523"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/product_brand?post=448523"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/product_cat?post=448523"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ab-marineservice.com\/en\/wp-json\/wp\/v2\/product_tag?post=448523"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
