The charge is raised when the exchange pump is bought and credited once the worn pump goes back. It is a bookkeeping line rather than a fittable part, and on its own it supplies nothing. Core numbers in this series run three thousand above the unit they belong to, so the pump this deposit stands against is part number 3803725. Every line in this run carries the same injection pump core name with no fitment against it, so the part number is the only thing that ties a deposit to a particular pump - take it from the unit being exchanged.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Core deposit line, not an injection pump you can fit\n \u003c\/li\u003e\n \u003cli\u003e\n  Belongs with the exchange unit, part number 3803725\n \u003c\/li\u003e\n \u003cli\u003e\n  Refunded when the old injection pump is returned\n \u003c\/li\u003e\n \u003cli\u003e\n  No engine application published against the line, so order by part number\n \u003c\/li\u003e\n \u003cli\u003e\n  Fuel System group\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n It exists to carry the core charge on the exchange rather than to do anything mechanical; the injection pump itself pressurises the fuel and times its delivery to each injector, which is what governs the engine's power and its idle.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injection pump being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  Far more fuel going back to the tank on the return than the engine should be spilling\n \u003c\/li\u003e\n \u003cli\u003e\n  Corrosion, scoring or lacquering found on the elements and delivery valves once the pump is opened\n \u003c\/li\u003e\n \u003cli\u003e\n  Rough or uneven running traced back past the injector to the pump element serving that cylinder\n \u003c\/li\u003e\n \u003cli\u003e\n  Idle hunting or surging, with the revolutions never settling\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  The charge is refunded when the worn injection pump is returned, so keep the old pump and send it back rather than scrapping it\n \u003c\/li\u003e\n \u003cli\u003e\n  Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3803725\n \u003c\/li\u003e\n \u003cli\u003e\n  The pump has to be timed to the engine's documented figure on refitting, and the system bled through before it will start cleanly\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Refundable core deposit - not a physical part\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53385728000292,"sku":"1021019","price":2530.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_1ffb5f20-d73c-4d73-969c-54e447450d02.jpg?v=1788082898","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3806725-injection-pump-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
