Radium's redesigned siphon system deletes the restrictive OEM venturi jet pump from the return path while still scavenging the far side of the tank, all OEM sensors are retained, and the factory feed line with its integrated fuel pressure sensor reconnects to one of the two 8AN ORB outlet ports. Fuel compatibility covers gasoline, E85, and methanol.

Both arrive together in the matching fuel hanger plumbing kits, which also carry a built-in check valve in the filter to hold pressure after shutdown; running without a plumbing kit means sourcing your own regulator, filter, and check valve. Pump selection drives the version choice: 20-1320 for AEM 50-1220 and brushless DW440 style pumps, 20-1322 for the Walbro F9000 series. Size the pumps with the 15 to 45 LPH jet pump consumption in mind, and plan wiring upgrades for multi-pump installs since the OEM controller wiring supports a single pump at best. Radium DIY fuel pump wiring kits handle the rest, one per pump.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x fuel pump hanger assembly in the selected pump compatibility version\u003c\/li\u003e\n\u003cli\u003eSAE quick connect fittings for OEM feed line and crossover line, both vehicle variations\u003c\/li\u003e\n\u003cli\u003e8AN ORB to 6AN male fittings for the second outlet and return ports\u003c\/li\u003e\n\u003cli\u003eTwo billet aluminum OEM level sensor mounts\u003c\/li\u003e\n\u003cli\u003eElectrical hardware for pumps and sensors\u003c\/li\u003e\n\u003cli\u003eNOT included: fuel pumps, fuel pressure regulator, post-pump fuel filter, pump wiring kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2008-2014 Cadillac CTS; 2008-2015 Cadillac CTS-V\u003c\/li\u003e\n\u003cli\u003e2010-2015 Chevrolet Camaro; 2009-2017 Chevrolet Caprice PPV; 2014-2017 Chevrolet SS\u003c\/li\u003e\n\u003cli\u003e2008-2009 Pontiac G8; Holden Commodore VE\/VF and Caprice equivalents\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAn aftermarket fuel pressure regulator and a low micron post-pump filter are required on every installation; both come in the Radium fuel hanger plumbing kits for the CTS-V (20-1325-03 \/ 20-1325-05)\u003c\/li\u003e\n\u003cli\u003eBosch 0 580 454 100 and stock CTS-V pumps have no internal check valve; run 2 full time with the OEM PCM\u003c\/li\u003e\n\u003cli\u003eProtec 11928, Fuelab 49614, and DW810 pumps require the 13-1187 pump base to fit the 20-1322 strainer\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Fits AEM 50-1220 \/ DW440 Brushless (20-1320)","offer_id":43700550631491,"sku":"20-1320","price":569.95,"currency_code":"USD","in_stock":true},{"title":"Fits Walbro F90000267\/274\/285 (20-1322)","offer_id":43700550664259,"sku":"20-1322","price":617.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/20-1322.jpg?v=1787341411","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-pump-hanger-2008-2017-gm-ls-cars-20-1320-20-1322","provider":"Tuned by Shawn","version":"1.0","type":"link"}
