It supersedes part number 859704 — a number now covered by three separate pipes in this listing group, 859937 for cylinder 2, 859938 for cylinder 3 and 859939 for cylinder 4. All three weigh the same 0.107 kg, so the cylinder number is the only thing that identifies them and weight is no guide at all.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cp\u003e\n Typically suits:\n\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta TMD22A\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD22A\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta MD22P\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  TMD, MD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  For cylinder number 2\n \u003c\/li\u003e\n \u003cli\u003e\n  Supersedes 859704, which is now split across three cylinder-specific pipes\n \u003c\/li\u003e\n \u003cli\u003e\n  0.107 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  3 applications on TMD and MD engines\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Carries injection-pressure fuel from its pump outlet to the injector on cylinder 2, holding the pressure wave that opens the injector.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Diesel weeping from a union nut that will not seal however hard it is tightened\n \u003c\/li\u003e\n \u003cli\u003e\n  Misfire or a knock on one cylinder that follows the pipe when it is swapped\n \u003c\/li\u003e\n \u003cli\u003e\n  Chafe mark or bright rub line where the pipe has touched another component\n \u003c\/li\u003e\n \u003cli\u003e\n  Cracking at the cone or behind the union nut\n \u003c\/li\u003e\n \u003cli\u003e\n  Union cone found bruised, ridged or picked up on removal\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Do not bend a delivery pipe to fit — the routing is part of its design and work-hardening it will crack the cone\n \u003c\/li\u003e\n \u003cli\u003e\n  Renew any clamps or spacers that separate the pipes; letting them touch will wear them through\n \u003c\/li\u003e\n \u003cli\u003e\n  Bleed the system and check every union with the engine running before closing the engine space\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔄 Supersession \u0026amp; Cross Reference\n\u003c\/h2\u003e\n\u003ch3\u003e\n OEM Supersession Chain\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  859937 → Supersedes 859704\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta part\n \u003c\/li\u003e\n \u003cli\u003e\n  Brand new\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied in original or equivalent packaging\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53385577529636,"sku":"166115G","price":265.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_c1ed943c-266c-4f59-a1d4-82438fecbce3.jpg?v=1788101298","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/859937-delivery-pipe-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
