Description_INV 98-02 GM F BODY TWIN 450LPH PUMP MOD
Description_ASC Drive the vehicle until the level in the tank is at or below 1/8 of a tank. To make tank removal and reinstall as easy as possible, the lower the fuel level the better.
Description_DES HOLLEY PUMP MODULE SYSTEM - Twin 450 LPH
Description_EXT Fits 1998-2002 Camaro / Firebird - Twin 450 LPH Pump Module
Description_MKT If you are looking to make some serious power with your 1998-2002 4th Gen F-body, the Holley modules feature billet pump flanges that connect to either single or dual 340 or 450 LPH pumps. All four of these options are compatible with gasoline and E85 and come pre-installed with new level and tank pressure sensors as well as provisions to connect to the factory EVAP system for EPA compliance.
Description_MKT Each module also comes with all the parts and pieces necessary to complete the installation. Included is a 3 x 11-inch Hydramat filter that leverages surface tension to draw from nearly any area that has contact with fuel eliminating starvation under hard acceleration or cornering. Also included is a new fuel pump gasket, wiring pigtails for the level sender and fuel pump, and fittings to connect to the factory quick connect feed and return lines. The modules are all return style, so don't forget to pick up an EFI pressure regulator (such as the 19-392 or 19-395) to complete your installation.
