2007 Silverado 5.3 Fuel Filter - Ask the GM Technician Dec 08, 2010The reason the fuel filter is in the tank is that 2004 GM trucks and later vehicles have a returnless fuel system to reduce fuel vapors along with cooler fuel and a bit more horsepower. The EPA has required the system and many MFR's have been using it for quite some time. My 2000 Jeep has 116000 miles with the original pump and filter. 2007 CHEVROLET SUBURBAN 1500 5 V8 Fuel Filter | RockAuto RockAuto ships auto parts and body parts from over 300 manufacturers to customers' doors worldwide, all at warehouse prices.
