As a leading OE supplier to the automotive industry, Delphi holds more than 30 OE-proprietary innovations and 150 patents in fuel module and pump design. As a result, our fuel pumps restore fast-pressure performance and system integrity to provide better pumping through less energy. Delphi fuel pumps feature internal springs for increased durability and enhanced stability, while a lower amperage draw places less load on a vehicle's electrical system. Our fuel pumps include a large volume reservoir to better handle low-fuel situations and vehicle cornering, as well as fuel-level, gold-filled sensors for improved corrosion resistance. Other benefits of our fuel pumps include consistent pump flow, an enhanced filtration system for longer pump life and an OE-service body harness and connector for superior performance, durability and ease of installation.VEHICLE FITMENT:2004 Buick Rainier,2003-2006 Cadillac Escalade ESV, 2002-2006 Cadillac Escalade,Escalade EXT, 2002-2005 Cadillac Escalade,2007 Chevrolet Silverado 1500 Classic V8, 2007 Chevrolet Express 1500,Silverado 1500 Classic, 2007 Chevrolet Silverado 1500 Classic,Silverado 1500 HD Classic,Silverado 2500 HD Classic,Silverado 3500 Classic, 2006-2007 Chevrolet Suburban 1500,2007 GMC Sierra 1500 Classic V8, 2007 GMC Savana 1500,Sierra 1500 Classic, 2007 GMC Sierra 1500 Classic,Sierra 1500 HD Classic,Sierra 2500 HD Classic,Sierra 3500 Classic, 2004-2007 GMC Savana 3500, 2003-2007 GMC Savana 1500, 2005-2006 GMC Sierra 1500,2003-2004 Isuzu Ascender,2003-2004 Isuzu Ascender 4.2L 5.3L
