Holley 12-363 Details

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.

Each module also comes with all the parts and pieces necessary to complete the installation. Included is a 3" x 11" 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.
