The \u003cstrong\u003e01-03 trucks run a return style fuel system\u003c\/strong\u003e, so that kit carries a regulator and gauge and ties the OEM return line to the regulator outlet. The \u003cstrong\u003e04-10 trucks are returnless\u003c\/strong\u003e, where an adjustable regulator has nothing to return to, so that kit substitutes an FPD-R pulse damper to steady pressure instead. Fitting the wrong one leaves you either with a regulator you cannot plumb or without the pressure control you expected.\u003c\/p\u003e\n\u003cp\u003eBoth kits are built specifically around the Radium 20-0862 rails, which are sold separately, and both include the swivel fittings needed to mate cleanly to the factory SAE quick connects.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e01-03 kit\u003c\/strong\u003e: 0-100psi gauge, direct mount regulator, 5\/32in vacuum hose, 1\/2in EFI hose, thermal insulation sleeve, 8AN ORB to 1\/8in NPT fitting, 7x 8AN ORB plugs, 8AN ORB to 8AN male fitting, 2x 1\/8in NPT plugs, 2x PushLok hose ends, 8AN ORB to 6AN ORB swivel union, 6AN ORB to 5\/16in SAE swivel, 8AN ORB to 8AN male swivel, 8AN ORB to 3\/8in SAE swivel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e04-10 kit\u003c\/strong\u003e: FPD-R direct mount pulse damper, 5\/32in vacuum hose, 1\/2in EFI hose, thermal insulation sleeve, 8x 8AN ORB plugs, 8AN ORB to 8AN male fitting, 2x PushLok hose ends, 8AN ORB to 8AN male swivel, 8AN ORB to 3\/8in SAE swivel\u003c\/li\u003e\n\u003cli\u003eNOT included: the fuel rails\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20-1062\u003c\/strong\u003e: 2001-2003 GM Vortec 8100 L18, return style fuel system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20-1162\u003c\/strong\u003e: 2004-2010 GM Vortec 8100 L18, returnless fuel system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRequires the Radium 20-0862 fuel rails, sold separately\u003c\/li\u003e\n\u003cli\u003eMatch the kit to your model year and fuel system type; the two are not interchangeable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"2001-2003, Return Style (20-1062)","offer_id":43700782825539,"sku":"20-1062","price":208.95,"currency_code":"USD","in_stock":true},{"title":"2004-2010, Returnless (20-1162)","offer_id":43700782858307,"sku":"20-1162","price":151.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/20-1062_65629190-516f-46f5-ac78-b06f7e6eb953.png?v=1787356453","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-rail-plumbing-kit-gm-vortec-8100-l18-big-block-20-1062-20-1162","provider":"Tuned by Shawn","version":"1.0","type":"link"}
