Fits the factory plastic tank used in 1998-2002 Camaro/Firebird (or an earlier 4th Gen F-body retrofitted with this tank). Includes a 3 x 11-inch HydraMat filter, new gasket, wiring pigtails, and fittings for the factory quick-connect feed and return lines. Drive the vehicle down until the fuel level is at or below 1/8 tank before removal to ease reinstallation. Since this is a return-style module, an EFI pressure regulator such as the Holley 19-392 or 19-395 is needed to complete the installation.
