Its job is to take the sharp edges off pressure ripple - the pulsing that a lift pump generates and that a cam-driven high pressure pump adds to every time it draws a charge - so the feed arriving at the high pressure pump is steadier than the one leaving the tank. On a modified system that ripple shows up as unsettled pressure readings and noise in the lines rather than as an obvious fault, which is why it is easier to design out than to chase later.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCustom fuel systems already plumbed in AN06, where the damper drops into the existing line run\u003c\/li\u003e\n\u003cli\u003eBuilds pairing an uprated lift pump with a cam-driven high pressure pump, where feed-side pulsing is at its worst\u003c\/li\u003e\n\u003cli\u003eFuel systems showing restless low side pressure readings that the regulator alone is not settling\u003c\/li\u003e\n\u003cli\u003eEngine bays where line noise and fuel system harshness are worth engineering out at build stage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat Pressure Ripple Does On The Low Side\u003c\/h2\u003e\u003cp\u003eA lift pump does not deliver a smooth column of fuel; it delivers a rapid series of pulses, and a cam-driven high pressure pump pulls against that supply in bursts of its own. The two interact along the feed line and the result is oscillation - pressure that swings around the value the regulator is holding. A damper gives that energy somewhere to go, which makes the pressure the high pressure pump sees closer to the pressure you specified, and takes some of the hammer out of the lines and fittings around it.\u003c\/p\u003e\u003ch2\u003ePlumbing It Into The Low Side\u003c\/h2\u003e\u003cp\u003eBoth ends are AN06, so on an AN-plumbed system it goes inline in the feed between the lift pump and the high pressure pump with two hose ends and no adapters. Stainless construction suits the fuels a modified system is likely to see, including high ethanol blends. This is a low pressure side component: it belongs in the feed line, not on the high pressure rail. It pairs naturally with a pump core such as the \u003ca href=\"\/products\/nostrum-nostrum-stanadyne-1150-250-high-pressure-fuel-pump-h116-1608\"\u003eStanadyne 1150-250\u003c\/a\u003e, which already takes its feed on an AN06 male inlet.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: low pressure side fuel pulsation damper\u003c\/li\u003e\n\u003cli\u003eSKU: L061-1551\u003c\/li\u003e\n\u003cli\u003eFittings: AN06 in, AN06 out\u003c\/li\u003e\n\u003cli\u003eMaterial: stainless steel\u003c\/li\u003e\n\u003cli\u003eSystem side: low pressure feed side only\u003c\/li\u003e\n\u003cli\u003eIncluded: damper only - hose ends, lines and mounting hardware are separate\u003c\/li\u003e\n\u003cli\u003eFitment type: chosen by fitting size, system side and line routing rather than by vehicle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm your feed line is AN06, or plan adapters into the run before ordering.\u003c\/li\u003e\n\u003cli\u003eFit it on the low pressure side between lift pump and high pressure pump; it is not a high pressure rail component.\u003c\/li\u003e\n\u003cli\u003ePlan a mounting point and line routing that keeps the damper supported rather than hanging on the hose ends.\u003c\/li\u003e\n\u003cli\u003eHose ends, line and clamps are not included - add them to the order alongside it.\u003c\/li\u003e\n\u003cli\u003eIf you are unsure whether pulsing is your issue, log low side fuel pressure first and talk to Hoonies about what you see.\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\u003eNostrum High Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eLow side fuel pressure pulsation damper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eL061-1551\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInlet Fitting\u003c\/th\u003e\n\u003ctd\u003eAN06\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutlet Fitting\u003c\/th\u003e\n\u003ctd\u003eAN06\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem Side\u003c\/th\u003e\n\u003ctd\u003eLow pressure (feed) side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncluded Items\u003c\/th\u003e\n\u003ctd\u003eDamper only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment Type\u003c\/th\u003e\n\u003ctd\u003eUniversal - matched by fitting size and line routing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eCan I fit this on the high pressure rail?\u003c\/h3\u003e\u003cp\u003eNo. It is designed for the low pressure feed side, between the lift pump and the high pressure pump.
