It is supplied bare, with no engine installation accessories or hardware, and Nostrum lists it for shop and installer use in minimum quantities of six. Buy it as a component for a direct injection fuel system you are designing around a specific pressure target - a swap, a race engine, or a platform where the standard pump ran out of pressure long before the injectors did.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDirect injection builds targeting rail pressures above the 250 bar ceiling of the smaller Stanadyne cores\u003c\/li\u003e\n\u003cli\u003eEngine builders and shops specifying pump, lines and drive as one designed system\u003c\/li\u003e\n\u003cli\u003eRace and development work where pressure headroom is the point rather than a bonus\u003c\/li\u003e\n\u003cli\u003eTrade buyers stocking cores for repeat custom fuel system builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat 350 Bar Means For The Rest Of The System\u003c\/h2\u003e\u003cp\u003eRail pressure is the lever that lets a direct injector empty itself in the short window it has, and lifting the ceiling from 250 to 350 bar moves that limit. It also moves the demands on everything downstream: hard lines, unions, seals and the rail itself all have to be specified for the working pressure, the cam drive has to carry the extra load, and the calibration has to be written for the pressure you are actually running. Choosing this core is a system decision, not a pump swap.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Stanadyne Inc, supplied by Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: bare high pressure fuel pump core\u003c\/li\u003e\n\u003cli\u003eSKU: H116-2000\u003c\/li\u003e\n\u003cli\u003ePump code: 1200-350 - 1200 flow class, 350 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eIncluded: pump core only, no installation accessories or hardware\u003c\/li\u003e\n\u003cli\u003eSupply: shop and installer line, minimum order quantity of six pumps\u003c\/li\u003e\n\u003cli\u003eBuyer checks: piston diameter, fitting sizes and cam drive requirements to be confirmed for your application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm the piston diameter, high and low pressure fitting sizes and cam drive requirement with Hoonies before ordering - this core is sold as a build component and the detail matters more than usual.\u003c\/li\u003e\n\u003cli\u003eSpecify lines, unions, seals and rail for 350 bar working pressure, not for the pressure your current system runs.\u003c\/li\u003e\n\u003cli\u003eThe low pressure supply has to keep the inlet fed at the flow this core will ask for.\u003c\/li\u003e\n\u003cli\u003eRail pressure control and the injector calibration both have to be written for the target pressure before the engine runs.\u003c\/li\u003e\n\u003cli\u003eNostrum supplies these in minimum quantities of six, which makes this a trade and build line rather than a single retail purchase.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eStanadyne Inc (supplied by Nostrum High Performance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eBare high pressure fuel pump core\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eH116-2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePump Code\u003c\/th\u003e\n\u003ctd\u003e1200-350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax Operating Pressure\u003c\/th\u003e\n\u003ctd\u003e350 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncluded Items\u003c\/th\u003e\n\u003ctd\u003ePump core only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum Order Quantity\u003c\/th\u003e\n\u003ctd\u003e6 pumps (shop and installer supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment Type\u003c\/th\u003e\n\u003ctd\u003eUniversal core for custom fuel system builds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs anything included with the pump?\u003c\/h3\u003e\u003cp\u003eNo. It is the bare core.
