The FPD-R covers 40 to 70psi; this FPD-XR covers 40 to 105psi. If your base pressure stays under 70psi there is usually no advantage to the extra range unit. The exception: if rising rate pressure exceeds 70psi but never passes 105psi and never falls under 40psi in vacuum, the XR lets you run without a vacuum line where the standard unit would need one.\u003c\/p\u003e\n\u003cp\u003eDampers mount at any angle, and for best results should mount directly onto the fuel rail. Some fuel systems need more than one, and some benefit from a damper on the return line. The 14-0600 adapter is here because it steps an 8AN ORB damper down to a 6AN port when the rail's port sizing does not match.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAnodized and laser engraved aluminum top\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum body with 3\/8in NPT male threads\u003c\/li\u003e\n\u003cli\u003eStainless steel hardware\u003c\/li\u003e\n\u003cli\u003e4mm ID rubber vacuum hose and vacuum hose Y-fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal, any 3\/8in NPT female threaded port\u003c\/li\u003e\n\u003cli\u003eThe 14-0600 adapter suits 6AN ORB female ports with 8AN ORB dampers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDampers CANNOT be used with mechanical fuel pumps.\u003c\/strong\u003e These create pressure pulses far too strong for the internal diaphragm and will rupture it in short order.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDampers CANNOT be used with direct injection.\u003c\/strong\u003e Direct injection high pressure pumps will likewise rupture the diaphragm.\u003c\/li\u003e\n\u003cli\u003eNPT threads require sealant\u003c\/li\u003e\n\u003cli\u003eCheck that you have space around the port for the damper body before ordering\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"FPD-XR, 3\/8in NPT (20-0179)","offer_id":43704124244035,"sku":"20-0179","price":94.95,"currency_code":"USD","in_stock":true},{"title":"6AN ORB Male to 8AN ORB Female Adapter (14-0600)","offer_id":43704124276803,"sku":"14-0600","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/DM_FPDs_b35dfe15-6548-4cd6-8b16-a3c311224833.jpg?v=1787405038","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fpd-xr-fuel-pulse-damper-and-orb-adapter-universal-20-0179-14-0600","provider":"Tuned by Shawn","version":"1.0","type":"link"}
