The kit provides the sealing components required for all five injectors in the D3 fuel system, including the diesel return O-ring, retainer-plate O-ring, and copper injector sealing washer. These seals should be replaced any time an injector is removed — reusing old seals risks fuel-return seepage and combustion leakage at the injector seat.\u003c\/p\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDiesel return O-ring (per injector)\u003c\/li\u003e\n\u003cli\u003eRetainer-plate O-ring (per injector)\u003c\/li\u003e\n\u003cli\u003eCopper injector sealing washer (per injector)\u003c\/li\u003e\n\u003cli\u003eQuantity: 1 kit covers all five D3 injectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D3-110I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-140A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-140I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-150I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-170A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-170I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-200A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-200I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-220A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-220I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eConfirm your complete engine model, generation suffix, and serial number against the Volvo Penta D3 fuel injector and delivery pipe diagram before ordering.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eSerial Number Requirements\u003c\/h2\u003e\n\u003cp\u003eThis kit is specific to the D3 common-rail injector and delivery-pipe fuel system.

Both are typically needed during injector service.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThis is one of the easiest add-ons to recommend during any D3 injector service call — at $14.40 for a full five-injector seal set, it’s a straightforward upsell that prevents post-service fuel leaks. The most common issue is customers removing injectors and reusing the old seals to save time, then dealing with return-fuel seepage or combustion leakage after reassembly. It’s also worth recommending the retaining clamp (31272772) at the same time, since clamps are often damaged during removal and should be inspected before reuse.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563998183460,"sku":"31272771","price":14.4,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/970ef211-6791-4b48-8dea-35df440c66d2.png?v=1787521696","url":"https:\/\/marisolmarine.com\/products\/volvo-452","provider":"Marisol Marine Company","version":"1.0","type":"link"}
