If your 4700 is cranking longer than it should before starting, losing power under load, or stalling at idle after sitting, a worn transfer pump that can no longer deliver consistent fuel pressure from the tank to the injection system is a common cause.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the T444E Relies on a Dedicated Transfer Pump\u003c\/h2\u003e\n\u003cp\u003eThe \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/International_Harvester\"\u003eInternational Harvester\u003c\/a\u003e 4700 was built as a medium-duty work truck, and the 7.3L V8 T444E diesel that powers many of them needs fuel delivered at a steady pressure well above what gravity alone can provide, especially once fuel has to travel from the tank through the filter and up to the injection pump. The transfer pump is what does that job, pulling fuel from the tank and pushing it through the system at the pressure the injection pump needs to work correctly, and when it weakens with age, the entire fuel system downstream starts running lean or inconsistent even if every other component is healthy.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCross-referenced to part number 81863ZZ\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the 1995-2002 International 4700, 7.3L V8 T444E\u003c\/li\u003e\n\u003cli\u003eBacked by a 12-month manufacturer warranty\u003c\/li\u003e\n\u003cli\u003eNew unit, not remanufactured or rebuilt\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: 81863ZZ\u003c\/li\u003e\n\u003cli\u003eApplication: International 4700, 7.3L V8 T444E\u003c\/li\u003e\n\u003cli\u003eType: Fuel transfer pump\u003c\/li\u003e\n\u003cli\u003eWarranty: 12 months\u003c\/li\u003e\n\u003cli\u003eCondition: New\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFits the 1995-2002 International 4700 equipped with the 7.3L V8 T444E diesel engine. Because International offered the 4700 chassis with more than one engine option across this production run, it's worth confirming your specific truck has the T444E before ordering, since other engine options in the same chassis use a different fuel delivery setup.\u003c\/p\u003e\n\n\u003ch2\u003eSigns Your Transfer Pump Is Failing\u003c\/h2\u003e\n\u003cp\u003eA weakening transfer pump on a T444E-equipped 4700 usually shows up gradually rather than all at once: longer cranking times before the engine catches, a noticeable loss of power when climbing grades or pulling a load, or a rough idle and occasional stalling once the truck has been running a while. Because these symptoms overlap with other fuel system issues like a clogged filter or failing injectors, checking fuel pressure at the pump before condemning other components can save time and unnecessary parts spending.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Fleet and Owner-Operators Replace This Part Proactively\u003c\/h2\u003e\n\u003cp\u003eA medium-duty truck like the 4700 is typically kept in active service well past the point where a passenger vehicle would be retired, and an unexpected fuel system failure on the road means a truck out of service and a load that isn't moving. Because a transfer pump failure tends to develop gradually before it fails outright, many fleet operators replace it as soon as early symptoms appear rather than waiting for a no-start situation at an inconvenient time, treating it as routine preventive maintenance on a truck that logs high annual mileage.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eReplacing this pump means relieving fuel system pressure first, disconnecting the fuel lines at the old pump, unbolting it from its mounting point, and installing the new pump with fresh sealing washers or gaskets at each fitting. Because diesel fuel systems are sensitive to air intrusion, bleeding the system properly after installation is an important step, and a truck that cranks longer than normal on first startup after the swap usually just needs additional bleeding rather than pointing to a bad part.\u003c\/p\u003e\n\n\u003ch2\u003eOrdering Information\u003c\/h2\u003e\n\u003cp\u003eThis fuel transfer pump is in stock and ships ready to install.
